GFS2: Remove gfs2_quota_change_host structure
There is only one place this is used, when reading in the quota changes at mount time. It is not really required and much simpler to just convert the fields from the on-disk structure as required. There should be no functional change as a result of this patch. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
