cfg80211: separate intersection section in __set_regdom()
So far the __set_regdom() code is pretty generic as the
intersection case is fairly straight forward; this will however
change when 802.11d support is added so lets separate intersection
code for now in preparation for 802.11d support.
This patch only has slight functional changes.
