st/nine: Resolve deadlock in surface/volume dtors when using csmt
Surfaces and Volumes can be freed in the worker thread. Without this patch, pending_uploads_counter could be non-zero in the Surfaces or Volumes dtor, leading to deadlock. Instead decrease properly the counter before releasing the item. Also avoid another potential deadlock if the item is not properly unlocked: Do not call UnlockRect which will cause deadlock, but free directly using the deadlock safe nine_context_get_pipe_multithread.
