From: Johannes Berg <johannes.berg@xxxxxxxxx>
When hostapd adds a station, it does so before sending the association
response frame, so that it can indicate the correct status code in the
response.
However, when this then fails, or the association response already is
a reject for some other reason, then there's no station entry and thus
no per-station management queue to send the response on and it must be
sent on the probe response queue. The code should therefore not warn.
In theory, we could check and warn if the status code is success, but
that seems excessive, so just relax the check to allow any association
response frames.
