rls(k): send 200ok for NOTIFY with subscription state termintated

- when rls module sends an un-SUBSCRIBE (expires=0), then the dialog structure is removed and the NOTIFY arriving later to confirm the termination of subscription does not find any record, resulting in no reply - the patch detects the subscribe-state terminated in NOTIFY requests and sends back 200ok - reported by Peter Dunkley
