[GFS2] Some further style changes
Introduce a couple of new constants which make the NFS filehandle sizes that GFS2 uses a bit clearer. Also fix one or two minor issues as per Jan Engelhardt's sixth email. Cc: Jan Engelhardt <jengelh@linux01.gwdg.de> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
