Fixed lp:963603 "Assertion `lock_type != TL_UNLOCK && (lock_type == TL_IGNORE || file->lock.type == TL_UNLOCK)' failed in ha_maria::store_lock with DML, triggers, views"


mysys/thr_lock.c:
  Ensure that all locks are marked as TL_UNLOCK in case of error (Safety fix)
sql/lock.cc:
  Ensure that all locks are marked as TL_UNLOCK in case of error
  (This is the real fix for lp:963603)
