v3dv: fix confusing nomenclature about DRM nodes

We have been using drm_render_device to refer to the render device and
drm_primary_device to refer to the display device, but that is confusing
because the render device also has a primary node (for legacy reasons),
so don't use primary to refer to the display device.
