sata_via: don't diddle with ATA_NIEN in ->freeze
vt6420 completely loses its ability to raise IRQ for ATAPI devices if
ATA_NIEN is diddled with in ->freeze. Further investigation is
necessary to determine whether this problem is shared on other
controllers but it doesn't seem to be at this point.
Make vt6420's ->freeze only clear IRQ to fix this problem. This makes
vt6420 relatively more prone to IRQ storms but the controller is way
too braindamaged to worry about that anyway.
