[GFS2] Remove inherited flags from exported flags.
We don't need the inherited flags since this action can be
implied by setting the flags on directories where they
wouldn't otherwise make sense. It reduces the number of extra
flags by two. Also updated the list of flags to take account of
one extra ext2/3 flag.
