I thought about this some more and I think neither behaviour is actually
correct with nl80211 drivers since they don't pass NoA data up. Unless,
of course, powersaving is disabled, the device doesn't support
multi-channel, etc.

I think this area generally needs a lot of work and this patch/hack
isn't really suitable for anything.
