intel: Use rb->Data and rb->RowStride to handle spans Y flipping.
This is already pointing at 0 or Height - 1 and with an appropriate pitch, so no need to recompute those values per customization of the spans code. Cuts 3 out of 21kb of the compiled size. Reviewed-by: Chad Versace <chad@chad-versace.us>
