Coverity found a number of places where we either do MAX(unsigned, 0) or
do assertions that a unsigned variable is >= 0. These do nothing, so
let us drop them all.
It also found a spot where we do `if (unsigned >= 0 && ...)`. Let us
also drop the unsigned >= 0 check.

Coverity complained about this. An error from `hkdf_sha512()` before uio
initialization will cause pointers to uninitialized memory to be passed
to `zio_crypt_destroy_uio()`. This is a regression that was introduced
by cf63739191. Interestingly, this never
affected FreeBSD, since the FreeBSD version never had that patch ported.
Since moving uio initialization to the top of this function would slow
down the qat_crypt() path, we only move the `memset()` calls to the top
of the function. This is sufficient to fix this problem.

Coverity complained about unchecked return values and unused values that
turned out to be unused return values.
Different approaches were used to handle the different cases of
unchecked return values:
* cmd/zdb/zdb.c: VERIFY0 was used in one place since the existing code
had no error handling. An error message was printed in another to
match the rest of the code.
* cmd/zed/agents/zfs_retire.c: We dismiss the return value with `(void)`
because the value is expected to be potentially unset.
* cmd/zpool_influxdb/zpool_influxdb.c: We dismiss the return value with
`(void)` because the values are expected to be potentially unset.
* cmd/ztest.c: VERIFY0 was used since we want failures if something goes
wrong in ztest.
* module/zfs/dsl_dir.c: We dismiss the return value with `(void)`
because there is no guarantee that the zap entry will always be there.
For example, old pools imported readonly would not have it and we do
not want to fail here because of that.
* module/zfs/zfs_fm.c: `fnvlist_add_*()` was used since the
allocations sleep and thus can never fail.
* module/zfs/zvol.c: We dismiss the return value with `(void)` because
we do not need it. This matches what is already done in the analogous
`zfs_replay_write2()`.
* tests/zfs-tests/cmd/draid.c: We suppress one return value with
`(void)` since the code handles errors already. The other return value
is handled by switching to `fnvlist_lookup_uint8_array()`.
* tests/zfs-tests/cmd/file/file_fadvise.c: We add error handling.
* tests/zfs-tests/cmd/mmap_sync.c: We add error handling for munmap, but
ignore failures on remove() with (void) since it is expected to be
able to fail.
* tests/zfs-tests/cmd/mmapwrite.c: We add error handling.
As for unused return values, they were all in places where there was
error handling, so logic was added to handle the return values.

Incorrectly sizing the array of hash locks used to protect the
dbuf hash table can lead to contention and reduce performance.
We could unconditionally allocate a larger array for the locks
but it's wasteful, particularly for a low-memory system.
Instead, dynamically allocate the array of locks and scale
it based on total system memory.
Additionally, add a new `dbuf_mutex_cache_shift` module option
which can be used to override the hash lock array size. This is
disabled by default (dbuf_mutex_hash_shift=0) and can only be
set at module load time. The minimum target array size is set
to 8192, this matches the current constant value.
Note that the count of the dbuf hash table and count of the
mutex array were added to the /proc/spl/kstat/zfs/dbufstats
kstat.
Finally, this change removes the _KERNEL conditional checks.
These were not required since for the user space build there
is no difference between the kmem and vmem interfaces.

[bash]# cat /sys/module/zfs/parameters/zfs_blake3_impl
cycle fastest generic sse2 [sse41] avx2

```
[bsd]# sysctl vfs.zfs.blake3_impl
vfs.zfs.blake3_impl: cycle [fastest] generic sse2 sse41 avx2
[bsd]# sysctl vfs.zfs.blake3_impl=sse2

The assertions are racy and the use of `membar_exit()` did nothing to

The helpers use atomic functions, so we cleverly get values from the
atomics that we can use to ensure that the assertions operate on the
correct values.
We also use `membar_producer()` prior to decrementing reference counts
so that operations that happened prior to a decrement to 0 will be
guaranteed to happen before the decrement on architectures that reorder
atomics.
This also slightly improves performance by eliminating unnecessary
reads, although I doubt it would be measurable in any benchmark.

bits are set, a value such as `((1 << 36) + 1)` would truncate to 1,
which is wrong.

change the order in which we call arc_buf_destroy() and
dbuf_prefetch_fini() to match the rest of the function. This prevents
the theoretical situation from being a possibility.
Also, we have a few return statements with a value, despite this being a
