lockdep: Fix lockdep annotation for pipe_double_lock() The presumed use of the pipe_double_lock() routine is to lock 2 locks in a deadlock free way by ordering the locks by their address. However it fails to keep the specified lock classes in order and explicitly annotates a deadlock. Rectify this.
