GFS2: Add "top dir" flag support
This patch adds support for the "top dir" flag. Currently this is unused but a subsequent patch is planned which will add support for the Orlov allocation policy when allocating subdirectories in a parent with this flag set. In order to ensure backward compatible behaviour, mkfs.gfs2 does not currently tag the root directory with this flag, it must always be set manually.
