Sergei Golubchik d6d7e169fb MDEV-12669 Circular foreign keys cause a loop and OOM upon LOCK TABLE ...

table_already_fk_prelocked() was looking for a table in the wrong
list (not the complete list of prelocked tables, but only in its tail,
starting from the current table - which is always empty for the last
added table), so for circular FKs it kept adding same tables to the list
indefinitely.
