(cherry picked from commit 41133c9794)
- Add a zfs_exit() call in an error path, otherwise a lock is leaked.
- Remove the fid_gen > 1 check. That appears to be Linux-specific:
zfsctl_snapdir_fid() sets fid_gen to 0 or 1 depending on whether the
snapshot directory is mounted. On FreeBSD it fails, making snapshot
dirs inaccessible via NFS.

A followup to d7a67402a8
For `mount -t zfs -o opts ds mp` command line
some implementations of `mount(8)`, e. g. Busybox in Debian
work as follows:
```
newfstatat(AT_FDCWD, "ds", 0x7fff826f4ab0, 0) = -1
mount("ds", "mp", "zfs", MS_SILENT, NULL) = 0
```
The logic above skips completely `mount.zfs` and prevents us
from reading filesystem properties and applying mount options.
For comparison, the coreutils `mount(8)` implementation does:
```
openat(AT_FDCWD, "/proc/filesystems", O_RDONLY|O_CLOEXEC) = 3
// figure out that zfs is a `nodev` filesystem and look for a helper
newfstatat(AT_FDCWD, "/sbin/mount.zfs" ...) = 0
execve("/sbin/mount.zfs" ...) = 0
```
Using `mount.zfs` in initramfs would help circumvent deficiencies
of some of `mount(8)` implementations. `mount -t zfs` translates
to `mount.zfs` invocation, except for cases when explicitly disabled
by `-i`.

Closes#13305
(cherry picked from commit 35d81a75a8)
Clang's static analyzer found a bad free caused by skein_mac_atomic().
It will allocate a context on the stack and then pass it to
skein_final(), which attempts to free it. Upon inspection,
skein_digest_atomic() also has the same problem.
These functions were created to match the OpenSolaris ICP API, so I was
curious how we avoided this in other providers and looked at the SHA2
code. It appears that SHA2 has a SHA2Final() helper function that is
called by the exported sha2_mac_final()/sha2_digest_final() as well as
the sha2_mac_atomic() and sha2_digest_atomic() functions. The real work
is done in SHA2Final() while some checks and the free are done in
sha2_mac_final()/sha2_digest_final().
We fix the use after free in the skein code by taking inspiration from
the SHA2 code. We introduce a skein_final_nofree() that does most of the
work, and make skein_final() into a function that calls it and then
frees the memory.

When reviewing #13875, I noticed that our FreeBSD code has an issue
where it converts from `int64_t` to `int` when calling
`vnlru_free{,_vfsops}()`. The result is that if the int64_t is `1 <<
36`, the int will be 0, since the low bits are 0. Even when some low
bits are set, a value such as `((1 << 36) + 1)` would truncate to 1,
which is wrong.
There is protection against this on 32-bit platforms, but on 64-bit
platforms, there is no check to protect us, so we add a check.

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.

When iterating through children physical ashifts for vdev, prefer
ones above the maximum logical ashift, that we can actually use,
but within the administrator defined maximum.
When selecting top-level vdev ashift, do not set it to the defined
maximum in case physical ashift is even higher, but just ignore one.
Using the maximum does not prevent misaligned writes, but reduces
space efficiency. Since ZFS tries to write data sequentially and
aggregates the writes, in many cases large misanigned writes may be
not as bad as the space penalty otherwise.
Allow internal physical ashifts for vdevs higher than SHIFT_MAX.
May be one day allocator or aggregation could benefit from that.
Reduce zfs_vdev_max_auto_ashift default from 16 (64KB) to 14 (16KB),
so that ZFS may still use bigger ashifts up to SHIFT_MAX (64KB),
but only if it really has to or explicitly told to, but not as an
"optimization".
There are some read-intensive NVMe SSDs that report Preferred Write
Alignment of 64KB, and attempt to build RAIDZ2 of those leads to a
space inefficiency that can't be justified. Instead these changes
make ZFS fall back to logical ashift of 12 (4KB) by default and
only warn user that it may be suboptimal for performance.

Users were seeing floods of `config_sync` events when autoexpand was
enabled. This happened because all "disk status change" udev events
invoke the autoexpand codepath, which calls zpool_relabel_disk(),
which in turn cause another "disk status change" event to happen,
in a feedback loop. Note that "disk status change" happens every time
a user calls close() on a block device.
This commit breaks the feedback loop by only allowing an autoexpand
