virtio_net: exploit napi_complete_done() return value
Since commit 364b6055738b ("net: busy-poll: return busypolling status to drivers"), napi_complete_done() returns a boolean that can be used by drivers to conditionally rearm interrupts. This patch changes virtio_net to use this boolean to avoid a bit of overhead for busy-poll users. Jason reports about 1.1% improvement for 1 byte TCP_RR (burst 100).
