drm/sched: Fix fence reference count leak
commit a952f1ab696873be124e31ce5ef964d36bce817f upstream.
The last_scheduled fence leaks when an entity is being killed and adding
the cleanup callback fails.
Decrement the reference count of prev when dma_fence_add_callback()
fails, ensuring proper balance.
