Merge branch 'virtio-net-fix-total-qstat-values'

Jakub Kicinski says:

====================
virtio-net: fix total qstat values

Another small fix discovered after we enabled virtio multi-queue
in netdev CI. The queue stat test fails:

  # Exception| Exception: Qstats are lower, fetched later
  not ok 3 stats.pkt_byte_sum

The queue stats from disabled queues are supposed to be reported
in the "base" stats.
