P2P: Assume GO Negotiation failed if GO Neg Conf wait times out
With this patch applied, the GO negotiation sequence effectively
becomes a one-shot process. Once the GO neg response is transmitted,
and a go neg confirm frame is not seen in 100ms, the negotiation
This is problematic in various scenarios:
1. The GO neg response might not have been acked by the peer. The Tx
status of this frame is currently ignored. In general this is ok -
since the peer maybe got it but switched the channel before the ack.
Unfortunately if the peer didn't get it, the negotiation will fail.
2. Some devices (namely the Galaxy Nexus device) find the 100ms
timeout too harsh. Sometimes 200ms+ go by before a negotiation confirm
When this patch is reverted, p2p works well.
