block: move more syncing and invalidation to delete_partition
Move the calls to fsync_bdev and __invalidate_device from del_gendisk to delete_partition. For the other two callers that check that there are no openers for the delete partitions(s) the callouts are a no-op as no file system can be mounted, but this keeps all the cleanup in one place.
