Fix hidl p2p network register & notifyStaApAuth

Added a 'registerNetwork' call to the persistent_group_added
notification within supplicant (and unregister to group removed).
Changed notifyApStaAuthorized to now send p2pCallbacks from the parent
interface theyre received on, instead of the dynamic GO child iface.
