direct-io: be sure to assign dio->bio_bdev for both paths btrfs sets ->submit_io(), and we failed to set the block dev for that path. That resulted in a potential NULL dereference when we later wait for IO in dio_await_one(). Reported-by: kernel test robot <ying.huang@linux.intel.com> Signed-off-by: Jens Axboe <axboe@fb.com>
