P2P: Allow wildcard service discovery from DBus API

Browse source 
Using the socket command interface, it is possible to pass a NULL dst to
wpas_p2p_sd_request, however you could not do so using the D-Bus API,
since it required a valid Peer object path. This patch changes the
behavior, so that if the "peer_object" is missing from the parameters,
a NULL dst is passed to wpas_p2p_sd_request.
