    afr: Drop compatibility lock for data self-heal

    Backport of http://review.gluster.org/#/c/12602/

    In glusterfs 3.4 and older, AFR did not take locks in self-heal domain
    during data self-heal. So this compat lock in data domain was added to
prevent
    older clients from trying to heal a file while an existing self-heal was
going
    on by a newer client. But the side effect was that all appending writes
(which
    take full locks in data domain) from mounts would be stalled until
self-heal
    was complete.

    Since glusterfs 3.4 is not supported anymore, remove the compat lock.
