Fix Status Code in TKIP countermeasures case 

The previously used WLAN_REASON_MICHAEL_MIC_FAILURE (14) value as a
response to Authentication frame or (Re)Association Request frame is not
correct since the resp value is encoded in the Status Code (not Reason
Code) field. Status Code 14 is WLAN_STATUS_UNKNOWN_AUTH_TRANSACTION
which is really what this value would have meant in the response frames.

There is no Michael MIC failure status code, so have to use the generic
"Unspecified failure" (1) reason code for these cases.
