Subject: [PATCH] virtio: silence compiler warning

gcc 4.8.5 emits the following false positive:

drivers/virtio/virtio_ring.c: In function 'vring_create_virtqueue':
drivers/virtio/virtio_ring.c:1032:5: warning: 'queue' may be used uninitialized in this function [-Wmaybe-uninitialized]

Silence it.
