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.

 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,
