Wong xfs_repair has a very old check that evidently excuses the AG 0 inode btrees pointing to blocks that are already marked XR_E_INUSE_FS* (e.g. AG headers). mkfs never formats filesystems that way and it looks like an error, so purge the check. After this, we always complain if inodes overlap with AG headers because that should never happen. Signed-off-by: Darrick J.
