Subject: [PATCH] bio: fix __bio_copy_iov() handling of bio->bv_len

The commit c5dec1c3034f1ae3503efbf641ff3b0273b64797 introduced
__bio_copy_iov() to add bounce support to blk_rq_map_user_iov.

__bio_copy_iov() uses bio->bv_len to copy data for READ commands after
the completion but it doesn't work with a request that partially
completed. SCSI always completes a PC request as a whole but seems
some don't.
