Why would we care? We only keep the preset_chandef thing around because
hostapd (currently) doesn't pass the frequency to START_AP/the first
SET_BEACON, but after that this doesn't matter. And when you shut down
hostapd, and restart it, then it'll set the preset_chandef again through
explicitly setting the channel.

So in which case would we care? Who would ever STOP_AP and then START_AP
without a new frequency?
