P2P: Set P2P_DEV_PEER_WAITING_RESPONSE from TX status callback 

Commit fb8984fd6f added a mechanism to
skip the Listen state when the peer is expected to be waiting for us to
initiate a new GO Negotiation. However, this flag was set when building
the GO Negotiation Response frame with status 1 regardless of whether we
managed to send that frame or peer receive it. This could result in GO
Negotiation failures in cases where the peer did not receive the
response and Listen channels of the devices were different. Fix this by
setting the flag only after TX status indicating success has been
received.

This fixes frequent failures shown for the test_grpform_pbc hwsim test
case.
