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).
Fixes: c9a11c23ceb6 ("igc: Add netdev")
