block: consolidate __invalidate_device and fsync_bdev
We currently have two interfaces that take a block_devices and the find a mounted file systems to flush or invaldidate data on it. Both are a bit problematic because they only work for the "main" block devices that is used as s_dev for the super_block, and because they don't call into the file system at all. Merge the two into a new bdev_mark_dead helper that does both the syncing and invalidation and which is properly documented. This is in preparation of merging the functionality into the ->mark_dead holder operation so that it will work on additional block devices used by a file systems and give us a single entry point for invalidation of dead devices or media. Note that a single standalone fsync_bdev call for an obscure ioctl remains for now, but that one will also be deal with in a bit.
