ath11k_nss: WAR for association failure issue with WDS

Browse Source 
Every 100 milliseconds, the station sends an "association request" and
the AP adds the peer and the AP responds to the station with an
"association response".

But "association response" takes time to reach the station. Because of
this, the station sends another "association request" to the AP.

In the second associate request, the AP removes the peer and re-adds
the station. Meanwhile, "association response" is reached to station
and station sends "QoS NULL" frame to AP.

The moment the station sends a QoS NULL frame to the ap, the peer on
the AP is deleted and the AP sends a de-authentication to the station.

To fix this issue, increased the assoc timeout period from 100 milli-
seconds to 500 milli seconds.
