net/virtio: allocate vrings on device NUMA node

When a guest is spanned on multiple NUMA nodes and
multiple Virtio devices are spanned onto these nodes,
we expect that their ring memory is allocated in the
right memory node.

Otherwise, vCPUs from node A may be polling Virtio rings
allocated on node B, which would increase QPI bandwidth
and impact performance.
