Subject: [PATCH 399/449] glusterd: coverity fixes
1400775 - USE_AFTER_FREE
1400742 - Missing Unlock
1400736 - CHECKED_RETURN
1398470 - Missing Unlock
Missing unlock is the tricky one, we have had annotation added, but
coverity still continued to complaint. Added pthread_mutex_unlock to
clean up the lock before destroying it to see if it makes coverity
happy.
