P2P: Improve handling of p2p_connect-auto fallback

Browse source 
Commit aa9bb7644b improved robustness
of p2p_connect-auto mechanism by using older scan results to help in
determination whether the peer was operating a GO. Improve this by
accepting new GO information from scan-for-WPS-provisioning results
even if the GO is not yet ready for WPS.

In addition, fix an issue where Provision Discovery exchange timeout
could have left offchannel TX operation in progress when the fallback
was used.
