[PATCH v1] dpdk-devbind.py: Virtio interface issue.

This change is required to have the interface name for virtio interfaces.
When we execute the status command the for virtio inerfaces we get
Sample output without the change:
0000:00:04.0 'Virtio network device' if= drv=virtio-pci unused=virtio_pci,igb_uio
Though for other drivers this works.
Sample output with the change:
0000:00:04.0 'Virtio network device' if=eth0 drv=virtio-pci unused=virtio_pci,igb_uio
