After firmware update for Intel-SA-00086, got "re-key has failed." error

Hi I am using Dell Latitude 3570 model laptop and some time back i found that it is affected with Intel-SA-00086 vulnerability using the Tool provided by Intel!

So as to fix it i updated the firmware release by Dell from:

And after the updating the firmware i did re-check using intel's tool to verify if problem was fixed and got below message:
