Subject: [PATCH 26/32] hostapd: mtk: avoid setting beacon after wpa_supplicant
 stop the AP

Add a new variable 'stopped_by_supplicant' to indicate the AP
interface is currently stopped by co-locating STA interface.
After the STA interface finishes association with some other APs, it
will reload the co-locating AP interfaces and marks the
'stopped_by_supplicant' as 0.
