s1gw: correct handling of UE CONTEXT RELEASE REQUEST
By sending a UE CONTEXT RELEASE REQUEST, the eNB is requesting the MME to terminate the UE context. This procedure itself does not terminate the UE context nor the associated E-RABs. Therefore, the S1GW should not terminate E-RAB FSMs upon receiving this PDU.
This means that we should not be expecting PFCP sesstion(s) to be deleted in S1GW_ConnHdlr.f_ConnHdlr_ue_ctx_release_req().
