Adapters: fix notifyConnectingTo to match the new return type

The base WheelAdapter signature became
notifyConnectingTo(deviceName: String?): DecodeResult.ModelName?
on the p6-fixes side so the InMotionV2Adapter can surface the model
immediately on connect (instead of waiting for the info-bundle round
trip). The 5 new adapters in more-wheels-support still had Unit
returns. Each one now returns null after setting detectedModel; the
CompositeWheelAdapter propagates whichever inner adapter's result
through.
