P2PS: Add group SSID, if known, to the P2PS-PROV-DONE event
The new optional group_ssid=<hexdump> argument in the P2PS-PROV-DONE event can be used to help in identifying the exact group if there have been multiple groups with the same P2P Interface Address in short period of time. Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com>
