block: don't reorder requests in blk_add_rq_to_plug
commit e70c301faece15b618e54b613b1fd6ece3dd05b4 upstream.
Add requests to the tail of the list instead of the front so that they
are queued up in submission order.
Remove the re-reordering in blk_mq_dispatch_plug_list, virtio_queue_rqs
and nvme_queue_rqs now that the list is ordered as expected.
