[PATCH] xfs: add the inode directory type support to XFS_IOC_FSGEOM

[Mark Tinguely <tinguely@xxxxxxx>]

Add the inode type directory type support to XFS_IOC_FSGEOM
so that xfs_repair/xfs_info knows if the superblock v4 filesystem
enabled the feature.

Signed-off-by: Mark Tinguely <tinguely@xxxxxxx>
---
 v2 remove the extra 0 in the XFS_FSOP_GEOM_FLAGS_xxx entries.
