Subject: [PATCH review 35/85] gfs2: Remove the QUOTA_USER and QUOTA_GROUP defines

From: "Eric W. Biederman" <ebiederm@...ssion.com>

Remove the QUOTA_USER and QUOTA_GRUP defines.  Remove
the last vestigal users of QUOTA_USER and QUOTA_GROUP.

Now that struct kqid is used throughout the gfs2 quota
code the need there is to use QUOTA_USER and QUOTA_GROUP
and the defines are just extraneous and confusing.
