Based on inputs from hardware architects, only "scan signature failures"
should be treated as actual hardware/cpu failure.
Current driver, in addition, classifies "scan controller error" scenario
too as a hardware/cpu failure. Modify the driver to classify this situation
with a more appropriate "untested" status instead of "fail" status.
