Add a null check in ConnectivityManagerDelegate.getNetworkState

Add a null check in ConnectivityManagerDelegate.getNetworkState

ConnectivityManager.getNetworkInfo can return null if the Network is invalid.
This CL adds a null check so we don't crash with a NullPointerException when
invoking networkInfo.getType()
