If the GO is not found, we cannot send Provisioning Discovery Request frame and cannot really connect anyway. Since the Provisioning Discovery is a mandatory part, it is better to continue join-scan until the GO is found instead of moving to the next step where normal connection scan is used (PD would not be used from there). Use a limit of 10 scan attempts for p2p_connect join to avoid getting in infinite loop trying to join. If the GO is not found with those scans, indicate failure (P2P-GROUP-FORMATION-FAILURE) and stop the join attempt.
