virtio: move dev_to_virtio() to use container_of_const()
The driver core is changing to pass some pointers as const, so move
dev_to_virtio() to use container_of_const() to handle this change.
dev_to_virtio() now properly keeps the const-ness of the pointer passed
into it, while as before it could be lost.
