fs/block_dev.c: skip rw_page if bdev has integrity
If a block device has bio integrity enabled, rw_page will bypass the integrity payload, which is undesirable. Skip rw_page if this is the case. Currently brd and zram provide rw_page, and the proposed 'nd' drivers will too. Cc: Jens Axboe <axboe@fb.com> Cc: Martin K.
