Looks fine in general, but as mentioned before live would be a lot
easier if we simply made the root inode a local variable in
libxfs_mount.
In fact I wonder if we even want to do that, there seems very little
reason to even do the root inode iget there - the only caller requesting
it will fall back if it fails.
