ublk: don't mutate struct bio_vec in iteration
__bio_for_each_segment() uses the returned struct bio_vec's bv_len field
to advance the struct bvec_iter at the end of each loop iteration. So
it's incorrect to modify it during the loop. Don't assign to bv_len (or
bv_offset, for that matter) in ublk_copy_user_pages().
