GFS2: Banish struct gfs2_rgrpd_host
This patch moves the final field so that we can get rid of struct gfs2_rgrpd_host, as promised some time ago. Also by rearranging the fields slightly, we are able to reduce the size of the gfs2_rgrpd structure at the same time. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
