module: freebsd: avoid a taking a destroyed lock in zfs_zevent bits
At shutdown time, we drain all of the zevents and set the
ZEVENT_SHUTDOWN flag.  On FreeBSD, we may end up calling
zfs_zevent_destroy() after the zevent_lock has been destroyed while
the sysevent thread is winding down; we observe ESHUTDOWN, then back
out.

Events have already been drained, so just inline the kmem_free call in
sysevent_worker() to avoid the race, and document the assumption that
zfs_zevent_destroy doesn't do anything else useful at that point.

This fixes a panic that can occur at module unload time.
