MDEV-15556 MariaDB crash with big_tables=1 and CTE
This bug manifested itself when the optimizer chose an execution plan with
an access of the recursive CTE in a recursive query by key and ARIA/MYISAM
temporary tables were used to store recursive tables.
The problem appeared due to passing an incorrect parameter to the call of
instantiate_tmp_table() in the function With_element::instantiate_tmp_tables().
