block: bio_remaining_done() isn't unlikely
We use bio chaining during most I/Os these days due to the delayed bio splitting. Additionally XFS will start using it, and there is a pending direct I/O rewrite also making heavy use for it. Don't pretend it's always unlikely, and let the branch predictor do it's job instead. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@fb.com>
