net/virtio: fix PCI ops assignment

VIRTIO_OPS() macro relies on the port ID stored in the
virtio_hw struct. Issue is that it is used before being
assigned at init time. It results in all devices setting
ops on port ID 0, causing crash later when calling ops
for port IDs other than 0.

This patch ensures port ID assignment is done at early
primary process probe time, before it is being used.
