wifi: wireless: deny wireless extensions on MLO-capable devices
These are WiFi 7 devices that will be introduced into the market
in 2023, with new drivers. Wireless extensions haven't been in
real development since 2006. Since wireless has evolved a lot,
and continues to evolve significantly with Multi-Link Operation,
there's really no good way to still support wireless extensions
for devices that do MLO.
Stop supporting wireless extensions for new devices. We don't
consider this a regression since no such devices (apart from
hwsim) exist yet.
