Jouni Malinen aaeb9c98e6 P2P: Allow GO to be discovered based on Beacon frame
This fixes some P2P-join-a-group cases where GO may have been discovered
based on passive scan or non-P2P scan. P2P IEs may have been received
from a Beacon frame in such a case and that information can be used to
create a P2P peer entry, e.g., to allow provision discovery exchange to
be completed.
