Enable the head_errlog feature to remove errors
In case check_filesystem() does not error out and does not report
an error, remove that error block from error lists and logs
without requiring a scrub. This can happen when the original file and
all snapshots/clones referencing it have been removed.

Otherwise zpool status will still report that "Permanent errors have
been detected..." without actually reporting any of them.

To implement this change the functions introduced in corrective
receive were modified to take into account the head_errlog feature.

Before this change:
=============================
pool: test
 state: ONLINE
status: One or more devices has experienced an error resulting in data
        corruption.  Applications may be affected.
action: Restore the file in question if possible.  Otherwise restore the
        entire pool from backup.
   see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-8A
config:

        NAME                   STATE     READ WRITE CKSUM
        test                   ONLINE       0     0     0
          /home/user/vdev_a    ONLINE       0     0     2

errors: Permanent errors have been detected in the following files:

=============================

After this change:
=============================
  pool: test
 state: ONLINE
status: One or more devices has experienced an unrecoverable error.  An
        attempt was made to correct the error.  Applications are
unaffected.
action: Determine if the device needs to be replaced, and clear the
errors
        using 'zpool clear' or replace the device with 'zpool replace'.

          /home/user/vdev_a    ONLINE       0     0     2

errors: No known data errors
