P2P: Optimize provisioning step scan for join-a-group sequence

Browse source 
Copy the SSID and frequency of the selected group into go_params in
join-a-running-group case so that the scan optimization can be used for
the provisioning step similarly to the case of group formation. This
uses a specific SSID and a single channel scan to avoid unnecessary
frames during the step.
