mac80211: disallow band-switch during CSA
If the AP advertises a band switch during CSA, we will not have the right information to continue working with it, since it will likely (have to) change its capabilities and we don't track any capability changes at all. Additionally, we store e.g. supported rates per band, and that information would become invalid. Since this is a fringe scenario, just disconnect explicitly.
