[PATCH 04/10] P2PS: Save wps_prov_info on the responder side

[Ilan Peer]

From: Andrei Otcheretianski <andrei.otcheretianski at intel.com>

When device A sends PD response to device B, device A should save
wps_prov_info for device B. Not doing so would result in a redundant and
incorrect PD flow, e.g. when upon PROV-DISC-DONE event device
B starts a GO and device A should join it.
