virtio-net: fix total qstat values

Browse Source 
[ Upstream commit 001160ec8c59115efc39e197d40829bdafd4d7f5 ]

NIPA tests report that the interface statistics reported
via qstat are lower than those reported via ip link.
Looks like this is because some tests flip the queue
count up and down, and we end up with some of the traffic
accounted on disabled queues.

Add up counters from disabled queues.
