P2P: Do not allow P2P client connection without P2P IE from GO 

P2P-GROUP-STARTED event depends on having enough information about the
group available. To avoid incomplete information from being delivered to
upper layers, do not accept scan results without P2P IE (e.g., from a
non-P2P scan) for P2P client association process. This can be of use for
some join-a-group cases where non-P2P scans have generated the BSS entry
for the GO.
