Currently, whenever AP link is brought down via ieee80211_stop_ap() function, all stations connected to the sdata are flushed. However, in case of MLO there is a requirement to flush only stations connected to that link and not all. For instance - Consider 2 GHz and 5 GHz are AP MLD. Now due to some reason 5 GHz link of this AP is going down (link removal or any other case). All stations connected, even legacy stations connected to 2 GHz link AP would also be flushed. Flushing of other link stations is wrong. Fix this issue by passing self link ID to sta_flush() function. This would then only remove the stations which are still using the passed link ID as their link sta. Other stations will not be affected.
