md/raid1: round up to bdev_logical_block_size in narrow_write_error
This modifies raid1's narrow_write_error to round up block_sectors to the device's logical block size. This prevents sd complaining about "Bad block number requested" for non-512-byte sector disks. Signed-off-by: Nate Dailey <nate.dailey@stratus.com> Signed-off-by: NeilBrown <neilb@suse.de>
