drm/nouveau: fix regression causing ttm to not be able to evict vram
TTM assumes an error condition from man->func->get_node() means that
something went horribly wrong, and causes it to bail.
The driver is supposed to return 0, and leave mm_node == NULL to
signal that it couldn't allocate any memory.
