drm/nv50: initialize ramht_refs list for faked 0 channel
We need it for PFIFO_INTR_CACHE_ERROR interrupt handling, because nouveau_fifo_swmthd looks for matching gpuobj in ramht_refs list. It fixes kernel panic in nouveau_gpuobj_ref_find. Signed-off-by: Marcin Slusarz <marcin.slusarz@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
