Fix 4addr reassociation-without-deauthentication on AP 

Data connection was lost if a station reassociated without the STA entry
being cleaned up on the AP side. Fix this by moving reconfiguration of
the STA WDS parameters in association response callback to happen only
after the STA flags have been updated to associated stated.
