btrfs: raid56: submit the read bios from scrub_assemble_read_bios
Instead of filling in a bio_list and submitting the bios in the only
caller, do that in scrub_assemble_read_bios. This removes the
need to pass the bio_list, and also makes it clear that the extra
bio_list cleanup in the caller is entirely pointless. Rename the
function to scrub_read_bios to make it clear that the bios are not
only assembled.
