Yes, because the inode usage counts aren't guaranteed to be the same
between filesystems due to weirdness in the root inode counts.

Basically, ocfs2 charges an additional 2 root inode count right off the
bat, which screws up the golden output.  btrfs doesn't have user/group
quotas, so the reflink-quota tests only ever checked XFS in the past.

I'll fix it not to rely on -O csv.
