P2P: Clear pending group formation data on group removal

It was possible for the wpa_s->show_group_started and wpa_s->go_params
to be left set when a P2P group was removed before group formation had
completed. In case a separate P2P group interface was not used, this
could rsult in all future scans using the hardcoded DIRECT-* SSID and as
such, not find the network they were trying to find. Fix this by
clearing these P2P parameters on group removal.
