When thread is BF aborted by high priority service, ULL (user level locks need to be removed and released). Calling directly release of lock for MDL_EXPLICIT type doesn't clear also `thd->ull_hash`. Method `mysql_ull_cleanup` will properly clear all information about ULL locks for thread. Reviewed-by: Jan Lindström <jan.lindstrom@mariadb.com>
