For make_btrfs(), it's setting wrong buf size for last super block write
out.
The superblock size is always BTRFS_SUPER_INFO_SIZE, not
cfg->sectorsize.

And this makes mkfs.btrfs -f -s 8K fails.

Fix it to BTRFS_SUPER_INFO_SIZE.

Thanks goodness, this time it's not my super block checksum patches
causing bugs.
