FS#13186: IAP: Send periodic updates in mode 4 (Stefan Ott)

Devices in IAP mode 4 do not explicitly request specific notifications, thus they don't get *any* periodic notifications at the moment (in particular, they miss the track position updates that are supposed to be sent out every 500 ms).

The attached patch fixes this by skipping an early return for devices in IST_EXTENDED state.
