Andrei Otcheretianski b9da88d6c1 P2PS: Authorize any peer for P2PS method if interface address not known 
When P2PS PD with default P2PS method is done, the peer that becomes GO
should authorize the client. However, P2PS specification doesn't require
the client to include its intended interface address in PD
Request/Response. As a result, the P2P Client's interface address may not
be known and any address may need to be authorized.

Previously, client's P2P Device Address was used for authorization,
which is not correct when a dedicated interface is used for P2P Client.
This is not resulting in a connection failure, however it causes a
significant delay (until WPS_PIN_TIME_IGNORE_SEL_REG elapses). Fix this
by authorizing the intended interface address, if known; or any address,
if not known.
