P2P: Allow older scan results to improve p2p_connect-auto robustness
Previusly the peer was assumed to not be operating a GO if the BSS entry for it was not updated in the single scan run started by p2p_connect-auto. This is not very robust since a scan may miss the peer if either a Probe Request or Probe Response frame is lost. Improve robustness by assuming the peer is still operating the GO and starting the join operation. If the GO is not found during PD-for-join or the single-channel scans during the join, fall back to GO Negotiation. Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>
