Alan Somers 6fd87e1d8d Don't emit cksum_{actual_expected} in ereport.fs.zfs.checksum events
With anything but fletcher-4, even a tiny change in the input will cause
the checksum value to change completely.  So knowing the actual and
expected checksums doesn't provide much more information than "they
don't match".  The harm in sending them is simply that they bloat the
event.  In particular, on FreeBSD the event must fit into a 1016 byte
buffer.

Fixes #14717 for mirrored pools.
