MDEV-21903 FTS optimize thread aborts during shutdown

Browse source 
- This issue was caused by 5e62b6a5e0.
fts_optimize_callback() should free fts_optimize_wq and make it as NULL
when it receives FTS_MSG_STOP message. So that subsequent
fts_optimize_callback() doesn't fail with segmentation fault.
