P2P: Increase GO Negotiation timeouts

P2P: Increase GO Negotiation timeouts

There may be environments in which large number of devices are operating
on the social channels. In such cases, it is possible for the Action
frame TX operation wait for quite long time before being able to get the
frame out. To avoid triggering GO Negotiation failures, increase the
timeouts for GO Neg Req (with TX ACK) and GO Neg Resp (with or without
TX ACK as long as status=0) to 500 ms.
