P2PS: Re-factor wpas_p2p_get_go_group() and wpas_p2p_group_go_ssid()

Browse source 
Re-factor wpas_p2p_get_go_group() to:

1. Skip the dedicated P2P Device management interface if it is used.
2. Instead of iterating all the interface configured networks,
   only access the current_ssid pointer to check if the current
   interface is acting as a persistent P2P GO.

To avoid code duplication, also re-factor wpas_p2p_group_go_ssid()
to call wpas_p2p_get_go_group().
