MDEV-22317: SIGSEGV in my_free/delete_dynamic in optimized builds (ARIA)

Post push fix.

when "replicate_wild_do_table" and "replicate_wild_ignore_table" filters
and changed dynamically the filter list gets cleared but the corresponding
"wild_do_table_inited" and "wild_ignore_table_inited" flags are not getting
cleared.

Fix: Clear the flags.
