drm: virtio: replace reference/unreference with get/put

DRM core uses reference/unreference suffixes for refcounting
functions, but kernel uses get/put (e.g. kref_get/put()).
Replace reference/unreference with get/put for consistency
and also it's shorter.

The following cocci script was used to generate the patch:
