ccae03f337 drm/virtio: fix prime export for vram objects 
commit 16845c5d5409 ("drm/virtio: implement blob resources: implement
vram object") and commit c6069a02fa55 ("drm/virtgpu: Set PRIME export
function in struct drm_gem_object_funcs") landed from different trees,
resulting in prime export never working for vram objects.

16845c5d54 drm/virtio: implement blob resources: implement vram object 
A virtio-gpu vram object is based on range-based allocation.
No guest shmemfs backing, so we call drm_gem_private_object_init.

This is for host memory without any guest backing (atleast initially).
