igc: Fix returning wrong statistics
'igc_update_stats()' was not updating 'netdev->stats', so the returned statistics, for example, requested by: $ ip -s link show dev enp3s0 were not being updated and were always zero. Fix by returning a set of statistics that are actually being updated (adapter->stats64).
