P2PS: Save intended interface address after P2PS PD

Browse source 
One possible outcome of the P2PS PD is P2P GO/P2P Client. In this case,
one peer becomes a P2P GO and the P2P Client joins it. Since multiple
GOs may run simultaneously on the same P2P Device, the P2P Client should
join using the intended interface address.

To be able to find the device by the intended interface address, save it
during the PD.
