Initial IP configuration can happen during ACTIVATED state if both v4 and v6 are enabled, but one takes longer than the other. Thus various checks throughout the code for IP_CONFIG were incorrect since they depended on IP configuration only happening during the IP_CONFIG state. Fix that by using a separate state for IP config and using that state for various checks instead of the overall device state.
