[#MDEV-17314] Assertion `thd->transaction.stmt.is_empty()' failed in Locked_tables_list::unlock_locked_tables upon CREATE OR REPLACE TEMPORARY TABLE

Note: might be related to, or be a duplicate of, ~~MDEV-16794~~, but these assertion failures tend to be mixed up or partially fixed, so I'm filing it separately just in case.

--source include/have_innodb.inc

CREATE TEMPORARY TABLE t1 (a INT) ENGINE=InnoDB;

CREATE TEMPORARY TABLE t2 (b INT);

LOCK TABLE t2 READ;

--error ER_INVALID_DEFAULT

CREATE OR REPLACE TEMPORARY TABLE t1 (c INT DEFAULT '');
