Christoph Hellwig 26ecf243e4 btrfs: stop using write_one_page in btrfs_scratch_superblock
write_one_page is an awkward interface that expects the page locked and
->writepage to be implemented.  Replace that by zeroing the signature
bytes and synchronize the block device page using the proper bdev
helpers.
