FUJITA Tomonori aefcc28a3a bio: fix __bio_copy_iov() handling of bio->bv_len ...

The commit c5dec1c303 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.
