MDEV-11071 - Assertion `thd->transaction.stmt.is_empty()' failed in

Locked_tables_list::unlock_locked_tables

Similarly to regular DROP TABLE, don't leave locked tables mode if CREATE OR
REPLACE dropped temporary table but failed to cerate new one.

The problem is that there's no track of which temporary table was "locked" by
LOCK TABLES.
