In case of HE AP-STA link, ieee80211_send_nullfunc() will not send the QOS NULL packet to check if AP is still associated.
In this case, probe_send_count will be non zero and ieee80211_sta_work() will later disassociate the AP.
(although it didn't really send a test QOS NULL packet).
Fix is to decrement probe_send_count and not call ieee80211_send_nullfunc() in case of HE link.

Hope I solved all the SMTP server problems and patch is better now :)
