We don't maintain tx counters in rx stats any more. There's no need
for an extra container of rq stats.

I'm not thinking removing sq stat is needed but even if it is I want to
keep virtnet_rq_stats to avoid allocating unnecessary u64_stats_syncp on
stack in virtnet_receive. I would just remove virtnet_rx_stats if necessary.

It's a nop on 64bit machines. And an unsigned on 32bit. So it's overhead 
could be ignored I think.

It's not a big problem so that's OK. I just felt like you reverted
unnecessarily too much. Anyway it is already applied and I'm not
