 Qemu fails with below error when trying to run with virtio pmem:

 (qemu) qemu-system-x86_64: -device virtio-pmem-pci,memdev=mem1,id=nv1:
  device is modern-only, use disable-legacy=on

 This patch fixes this by forcing virtio 1 with virtio-pmem.

fixes: adf0748a49 ("virtio-pci: Proxy for virtio-pmem")
