igb: update stats before doing reset in igb_down
It was seen with repeated interface up/down testing that there was a large stray between the stats reported by the queues and the stats reported by the HW. It was found to be an issue in that hw stats were being reset without first being recorded. This change records the stats before wiping them from the system via the reset.
