bcache: Fix leak of bdev reference
commit 4b758df21ee7081ab41448d21d60367efaa625b3 upstream.
If blkdev_get_by_path() in register_bcache() fails, we try to lookup the
block device using lookup_bdev() to detect which situation we are in to
properly report error. However we never drop the reference returned to
us from lookup_bdev(). Fix that.
