Aleksey Midenkov a4996f951d MDEV-22563 Segfault on duplicate free of Item_func_in::array 
Same array instance in two Item_func_in instances. First Item_func_in
instance is freed on table close. Second one is freed on
cleanup_after_query().

get_copy() depends on copy ctor for copying an item and hence does
shallow copy for default copy ctor. Use build_clone() for deep copy of
Item_func_in.
