cfg80211: check iface combinations only when iface is running
Don't validate interface combinations on a stopped interface. Otherwise we might end up being able to create a new interface with a certain type, but won't be able to change an existing interface into that type. This also skips some other functions when interface is stopped and changing interface type.
