P2P: Fix a potential memory leak in a P2P+NFC corner case
Avoid memory leak due to previous allocation for ssid->ssid. It does not look like this is hit in normal cases, but at might be possible for the SSID to get set if the peer is present in previous scan results and WPS code ends up copying the SSID from there.
