        Fix Bug #53947 InnoDB: Assertion failure in thread 4224 in file .\sync\sync0sync.c line 324
        
        Destroy the rw-lock object before freeing the memory it is occupying.
        If we do not do this, then the mutex that is contained in the rw-lock
        object btr_search_latch_temp->mutex gets "freed" and subsequently
        mutex_free() from sync_close() hits a mutex whose memory has been
        freed and crashes.
