The Virtio rework series mistakenly moved the rte_pci_device
pointer to struct virtio_hw, which is shared between the two
processes. But this structure is per-process, so this change
made secondary process to try accessing primary process-only
memory, leading to a crash.
This patch reverts to proper behavior, by storing the
rte_pci_device pointer into the per-process
virtio_pci_internal struct. It also provides helper to get
the pointer from the virtio_hw struct pointer.

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.
