Shaohua Li 16d56e2fcc md/raid1: fix writebehind bio clone ...

After bio is submitted, we should not clone it as its bi_iter might be
invalid by driver. This is the case of behind_master_bio. In certain
situration, we could dispatch behind_master_bio immediately for the
first disk and then clone it for other disks.
