Don't search for volatile expr in find_em_expr_usable_for_sorting_rel While prepare_sort_from_pathkeys has to be concerned about matching up a volatile expression to the proper tlist entry, we don't need to do that in find_em_expr_usable_for_sorting_rel becausee such a sort will have to be postponed anyway.
