There can be many reasons for this to be logged (ap_handle_timer: The code
in there is a bit confusing, the sta->timeout_next is never changed in the
function and also there's no locking so assuming that no one changes that,
but still we do check STA_REMOVE multiple times).
2) any ctrl interface disconnect/deauth event (eg. wps_cancel when wps is
3) If AP has gone for a hard reboot this timer checks for sta == null and
issues a prev_auth_not_valid
4) Some security Handshake failure.
After any of the above event we schedule the timer
for AP_MAX_INACTIVITY_AFTER_* (5/30) for deauth and disassoc and then
ap_handle_timer is called which logs the above message.
