I'm just saying that we can use exactly the code in ib_destroy_cm_id, but
avoid calling ib_send_cm_rej in this one case:


        case IB_CM_REQ_RCVD:
        case IB_CM_MRA_REQ_SENT:
        case IB_CM_REP_RCVD:
        case IB_CM_MRA_REP_SENT:
+		if (noresponse)
+			cm_reset_to_idle(cm_id_priv);
                spin_unlock_irqrestore(&cm_id_priv->lock, flags);
+		if (noresponse)
                ib_send_cm_rej(cm_id, IB_CM_REJ_CONSUMER_DEFINED,
                               NULL, 0, NULL, 0);

So we get all the handling for free, just avoid sending out the MAD.
