Jens Axboe 6b6676da6b block: clear bio->bi_bdev when putting a bio back in the cache 
commit 11eb695feb upstream.

This isn't strictly needed in terms of correctness, but it does allow
polling to know if the bio has been put already by a different task
and hence avoid polling something that we don't need to.
