This object indicates the number of quota return requests
by the QS. QS may send this message to cause CSG to
return unused quota for the target service.
QS sends the quota return request when the validity timer
expires, this in turn triggers the CCR update. The DCCA server
grants quota in response to quota return request. This object is
deprecated and replaced by cGgsnSACsgStatsQuotaReturnReqs.
