[SCSI] block: fix bio_add_page misuse with rq_map_data
This fixes bio_add_page misuse in bio_copy_user_iov with rq_map_data, which only sg uses now. rq_map_data carries page frames for bio_add_pc_page. bio_copy_user_iov uses bio_add_pc_page with a larger size than PAGE_SIZE. It's clearly wrong. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Acked-by: Jens Axboe <jens.axboe@oracle.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
