cfg80211: ignore consecutive equal regulatory hints
We ignore regulatory hints for the same alpha2 if we already
have processed the same alpha2 on the current regulatory domain.
For a driver regulatory_hint() this means we copy onto its
wiphy->regd the previously procesed regulatory domain from CRDA
without having to call CRDA again.
