afr: prevent winding inodelks twice for arbiter volumes
Backport of https://review.gluster.org/#/c/glusterfs/+/21380/
Problem:
In an arbiter volume, if there is a pending data heal of a file only on
arbiter brick, self-heal takes inodelks twice due to a code-bug but unlocks
it only once, leaving behind a stale lock on the brick. This causes
the next write to the file to hang.
Fix:
Fix the code-bug to take lock only once. This bug was introduced master
with commit eb472d82a083883335bc494b87ea175ac43471ff
Thanks to Pranith Kumar K <pkarampu@redhat.com> for finding the RCA.
