drm/nouveau: remove fence wait code from deferred client work handler Fences attached to deferred client work items now originate from channels belonging to the client, meaning we can be certain they've been signalled before we destroy a client. This closes a race that could happen if the dma_fence_wait_timeout() call didn't succeed. When the fence was later signalled, a use-after-free was possible.
