The search_itree and search_queue functions should both
return either a pointer to a found lock or NULL.
Currently, search_itree just returns the contents of
data->lmd_lock, whether or not a lock was found.
search_queue will do the same under certain cirumstances.
Zero lmd_lock in both search_* functions, and also stop
searching in search_itree once a lock is found.
