wifi: mac80211: fix CSA processing while scanning
The channel switch parsing code would simply return if a scan is in-progress. Supposedly, this was because channel switch announcements from other APs should be ignored. For the beacon case, the function is already only called if we are associated with the sender. For the action frame cases, add the appropriate check whether the frame is coming from the AP we are associated with. Finally, drop the scanning check from ieee80211_sta_process_chanswitch.
