mac80211: clean up ieee80211_set_channel
There's no need for ieee80211_set_channel to check whether a change in configuration happened since ieee80211_hw_config() auto-detects it. Additionally, it's wrong to pretend the HT config for the BSS changed, it didn't, the BSS can't be up & running (AP beaconing etc.) when the channel type is changed anyway.
