P2P: Clear PEER_WAITING_RESPONSE on GO Negotiation success

Browse source 
Previously, this flag was cleared only in case of failed GO Negotiation.
That could leave the flag set for a peer and if a new group formation
was performed with the same peer before the entry expired, there was
increased risk of getting stuck in a state where neither peer replied to
a GO Negotiation Request frame if a GO Negotiation Response frame with
Status 1 was dropped.

The error sequence could happen in the go_neg_with_bss_connected test
case when timing was suitable to make the second GO negotiation drop a
pending TX Action frame if the GO Negotiation Response with Status 1 was
scheduled for transmission during a P2P scan and P2P_CONNECT was issued
before that scan got aborted.
