MDEV-5368: Server crashes in Item_in_subselect::optimize on ...
- convert_subq_to_sj() must connect child select's tables into
parent select's TABLE_LIST::next_local chain.
- The problem was that it took child's leaf_tables.head() which
is different. This could cause certain tables (in this bug's case,
child select's non-merged semi-join) not to be present in
TABLE_LIST::next_local chain. Which would cause non-merged semi-join
not to be initialized in setup_tables(), which would lead to
NULL pointer dereference.
