P2P: Add p2p_client_list support for FullMAC Persistent GO

Browse source 
Currently, FullMAC Persistent GO can't use p2p_client_list because its
own hapd->p2p_group is NULL at ap_sta_set_authorized(). This patch
changes the processing to use sta->p2p_ie instead of
p2p_group_get_dev_addr() on FullMAC GO.
