linux-next: build warning after merge of the vhost tree

Hi all,

After merging the vhost tree, today's linux-next build (powerpc
ppc64_defconfig) produced this warning:

drivers/net/virtio_net.c: In function 'start_xmit':
drivers/net/virtio_net.c:1695:15: warning: unused variable 'bytes' [-Wunused-variable]
 1695 |  unsigned int bytes = skb->len;
      |               ^~~~~

Introduced by commit

  b3634a892df4 ("virtio_net: disable cb aggressively")
