P2P: No duplicate AP-STA-CONNECTED/DISCONNECTED as global event

Browse source 
These events are sent as a special case to both the group interface and
"parent interface" (i.e., the interface that was used for managing P2P
negotiation). The latter is not really correct event, so get rid of it
with the new global control interface design where there is no need to
support legacy upper layer implementations.
