net: aquantia: get total counters from DMA block
aq_nic_update_ndev_stats pushes statistics to ndev->stats from system interface. This is not always good because it counts packets/bytes before any of rx filters (including mac filter). Its better to report the packet/bytes statistics from DMA counters which gives actual values of data transferred over pci. System level stats is still available via ethtool.
