D-Bus: Do not send network notification for all P2P groups

Previously, network added event was skipping during group formation.
However, this did not necessarily catch all cases of temporary P2P
network blocks. Check ssid->p2p_group to make this behavior more
consistent by avoiding all P2P groups.
