[PATCH 2/2] drm/etnaviv: Remove deprecated fence_ops->release()

[Philipp Stanner]

The dma_fence->ops->release() callback is deprecated because it prevents
drivers from unloading. All etnaviv does in its implementation is invoke
a kfree_rcu() on the fence.

The fence backend by now also frees fences with kfree_rcu() if
ops->release() is not implemented.

Remove the deprecated callback.
