Peter Zijlstra 023d43c7b5 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.
