block: use __bio_add_page in bio_copy_kern
Since the bio is allocated with the exact number of pages needed via
blk_rq_map_bio_alloc(), and the loop iterates exactly that many times,
bio_add_page() cannot fail due to insufficient space. Switch to
__bio_add_page() and remove the dead error handling code.
