Generic(V1): Fix emitting framesReceived when disconnected

When one of these plugins was used in the
CAN-Example, the frames received slot was
still called after disconnecting.

That made the example stuck and emitting
lots of "Cannot read frame as device is
not connected." messages.

This is mostly relevant for developers
though, as these plugins are not deployed.
