When there is no fault bit set in a fault register we skip the fault reporting section for that register. This also skips over saving that registers value. We save the value so we will not double report an error, but if an error clears then returns we will also not report it as we did not save the all cleared register value. Fix this by saving the fault register value in the all clear path.
