Use Device Password ID in WSC IE of Probe Request and Probe Response
frames to advertise immediate availability of WPS credentials per P2P
specification sections 3.1.2.1.1 (Listen State), 3.1.2.1.2 (Scan Phase),
and 3.1.2.1.3 (Find Phase).
For now, the Device Password ID is set only for the case where we are
active GO Negotiation with a specific peer. In practice, this means that
the Probe Response frames during pending GO Negotiation (whenever in
Listen state) indicate availability of the credential.
