MDEV-20483 trx_lock_t::table_locks is not a subset of trx_lock_t::trx_locks
Problem:
=======
Transaction left with nonempty table locks list. This leads to
assumption that table_locks is not subset of trx_locks. Problem is that
lock_wait_timeout_thread() doesn't remove the table lock from
table_locks for transaction.
Solution:
========
In lock_wait_timeout_thread(), remove the lock from table vector of
transaction.
