WPS: Move from WLAN_STA_MAYBE_WPS to WLAN_STA_WPS based on EAP messages 

If the station does not include WSC IE in Association Request, it
is marked with WLAN_STA_MAYBE_WPS flag. We can update that to
WLAN_STA_WPS if the station uses either of the WPS identity strings.
This enables some workarounds for WPS stations.
