Recently we found out xfs_repair were not repairing
root inode parent pointer when root inode is on short-form
and parent points to an invalid inode number (refer to:
"xfs_repair: Fix root inode's parent when it's bogus for sf
directory" on xfs-devel list).
This test checks if xfs_repair successfully repair the
filesystem in the scenario mentioned before.
