drm/nouveau: Fix error handling in nv50_disp_atomic_commit
Make it more clear that post commit return ret is really return 0,
and add a missing drm_atomic_helper_cleanup_planes when
drm_atomic_helper_wait_for_fences fails.
Fixes: 839ca903f12e ("drm/nouveau/kms/nv50: transition to atomic interfaces internally")
