Vicențiu Ciorbaru 0992be927e MDEV-13068 Crash in Item::split_sum_func2 with INSERT SELECT using window functions ...

When running setup fields during the final step of insert using select
the final setup_fields does not have any sum functions. Our current
condition for calling split_sum_func however would attempt to use an empty
NULL sum_func_list, if the item contained a window function.

The solution is to not perform another split_sum_func for the item
containing a window function if we do not actually have a sum_func_list.
