MDEV-15465 Server crash or ASAN heap-use-after-free in Item_func_match::cleanup upon using FT search with partitioning.

The Item_func_match::cleanup() uses table's internals so it's not safe to call it after the close_thread_tables(). Let's call it in st_select_lex::cleanup().

Oops. Agree, thanks. But why do you fix it in 10.3? Looks like a 5.5+ bug. Regards, Sergei Chief Architect MariaDB and security@mariadb.org
