Subject: ocfs2/dlm: clear refmap bit of recovery lock while doing local recovery cleanup
When recovery master down, dlm_do_local_recovery_cleanup() only remove the
$RECOVERY lock owned by dead node, but do not clear the refmap bit. Which
will make umount thread falling in dead loop migrating $RECOVERY to the
dead node.
