[FUI07] Stop making NetworkState with NetworkInfo from external callers

Follow-up from previous patch. This change stop accessing the
constructor that needs NetworkInfo to create NetworkState, which
is no longer accessible after ConnectivityService become
mainline module. Instead, pass a legacy network type which is
dedicated for the need of the type.
