libertas: fix changing interface type when interface is down
The recent changes to only power the device when the interface up introduced a bug: changing interface type, legal when the interface is down, performs device I/O. Fix this functionality by validating and recording the interface type when the change is requested, but only applying the change if/when the interface is brought up.
