From: Yu Kuai <yukuai3@xxxxxxxxxx>
Currently, raid0_make_request() will remap the original bio to underlying
disks to prevent disordered IO. Now that bio_submit_split_bioset() will put
original bio to the head of current->bio_list, it's safe converting to use
this helper and bio will still be ordered.
