MDEV-20471 Assertion during cleanup of failed CREATE TABLE LIKE <sequence>

Browse Source 
While cleaning up a failed CREATE TABLE LIKE <sequence>, `mysql_rm_table_no_locks`
erroneously attempted to remove all tables involved in the query, including
the source table (sequence).

Fix to temporarily modify `table_list` to ensure that only the intended
table is removed during the cleanup.
