[PATCH tip/core/rcu 08/13] rcu: Eliminate unused rcu_init_one() argument

[Paul E. McKenney]

Now that the rcu_state structure's ->rda field is compile-time initialized,
there is no need to pass the per-CPU rcu_data structure into rcu_init_one().
This commit therefore eliminates this now-unused paramter.
