There's a bunch of nouveau kernel details I don't know here but the
interface looks good and I prefer it to a #de

The flags field in drm_syncobj_find_fence() takes SYNCOBJ_WAIT flags
from the syncobj UAPI whereas sync->flags is from the nouveau UAPI. What
we actually want is 0 flags which tells it to just try to find the
fence and then return without waiting.
