xfs: use bdev_rw_virt in xfs_verify_media

Use bdev_rw_virt for reading data from disk.  This simply uses an
on-stack bio and bio_vec and removes the need to allocate an bio and
reset it for each iteration.  Because bdev_rw_virt returns a negative
errno, pass that on to xfs_verify_media_error to avoid a double
conversion.
