cfg80211: send stop AP event only due to internal reason
Commit "nl80211: send event when AP operation is stopped" added an event to notify user space that an AP interface has been stopped, to handle cases such as suspend etc. The event is sent regardless if the stop AP flow was triggered by user space or due to internal state change. This might cause issues with wpa_supplicant/hostapd flows that consider stop AP flow as a synchronous one, e.g., AP/GO channel change in the absence of CSA support. In such cases, the flow will restart the AP immediately after the stop AP flow is done, and only handle the stop AP event after the current flow is done, and as a result stop the AP again. Change the current implementation to only send the event in case the stop AP was triggered due to an internal reason.
