commit c3e0276c31ca8c7b8615da890727481260d4676f upstream.
Previously the code relied on device->pri to be NULL and to fail probing
later. We really should just return an error inside nvkm_device_ctor for
unsupported GPUs.
Fixes: 24d5ff40a732 ("drm/nouveau/device: rework mmio mapping code to get rid
of second map")
