[PATCH] drm/nouveau/fifo: make nvkm_runl_new() return error pointers

[Dan Carpenter <error27@gmail.com>]

All six callers expect error pointers instead of NULL so make the
nvkm_runl_new() return error pointers as expected.

Fixes: d94470e9d150 ("drm/nouveau/fifo: add common runlist/engine topology")
