P2P: Assume GO Negotiation failed if GO Neg Conf wait times out

Stop the connection attempt if GO Negotiation Confirm is not received
within 100 ms of the GO Negotiation Response getting acknowledged.
Previously, we would have continued trying to connect to the peer even
in this case which could result in confusing second GO Negotiation
Request frame and unnecessarily long wait before indicating failure.
