The plan is use have both shmem and virtual "vram" running
side-by-side in virtio-gpu. It looks like we'll eventually use
struct drm_gem_object as a base class, and we'll need to convert
to shmem and vram objects on the fly. As a first step, add a
virtio_gpu_is_shmem helper. Thanks to kraxel for suggesting this
approach on Gitlab.
