[GFS2] Extended attribute code style changes
As per Jan Engelhardt's request and also a few of my own. It has been possible to add a few most const to the code as a result of the change in gfs2_ea_name2type. Cc: Jan Engelhardt <jengelh@linux01.gwdg.de> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
