DESCRIPTION
Marks all tables in the list which were used by current substatement
(they are marked by its query_id) as free for reuse.
NOTE
The reason we reset query_id is that it's not enough to just test
if table->query_id != thd->query_id to know if a table is in use.
For example
SELECT f1_that_uses_t1() FROM t1;
In f1_that_uses_t1() we will see one instance of t1 where query_id is
set to query_id of original query.
