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

Browse Source 
Partition engine FT keys are implemented in such a way that
the FT function's cleanup() methods use table's internals.
So calling them after close_thread_tables is unsafe.
