drm/virtio: implement context init: stop using drv->context when creating fence
The plumbing is all here to do this. Since we always use the
default fence context when allocating a fence, this makes no
functional difference.
We can't process just the largest fence id anymore, since it's
it's associated with different timelines. It's fine for fence_id
260 to signal before 259. As such, process each fence_id
individually.
