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