drm/nouveau: fence: fix type cast warning in nouveau_fence_emit()

Browse source 
Fix the following warning.

  drivers/gpu/drm/nouveau/nouveau_fence.c:210:45: sparse: sparse:
  incorrect type in initializer (different address spaces)
  @@     expected struct nouveau_channel *chan
  @@     got struct nouveau_channel [noderef] __rcu *channel

We're just about to emit the fence, there is nothing to protect against
yet, hence it is safe to just cast __rcu away.
