doc: Fix diagram references in memory-ordering document
The three diagrams describing rcu_gp_init() all spuriously refer to the same figure, probably due to a copy/paste issue. This commit fixes these references. Signed-off-by: Frederic Weisbecker <frederic@kernel.org> Signed-off-by: Paul E. McKenney <paulmck@kernel.org>

The final ``rcu_gp_init()`` pass through the ``rcu_node`` tree traverses
breadth-first, setting each ``rcu_node`` structure's ``->gp_seq`` field
to the newly advanced value from the ``rcu_state`` structure, as shown
in the following diagram.

This change will also cause each CPU's next call to
``__note_gp_changes()`` to notice that a new grace period has started,
