From: Xinming Hu <huxm@xxxxxxxxxxx>
When hostapd is killed with Ctrl+C before cac get completed,
stop_ap handler will not be called, thus priv->wdev.cac_started
flag remains set.
Hostapd restart attempt will be failed in this case with device
busy error. This patch aborts cac in del_station handler to
handle this corner case.
