rcu: Simplify rcu_pending()/rcu_check_callbacks() API
All calls from outside RCU are of the form:
if (rcu_pending(cpu))
rcu_check_callbacks(cpu, user);
This is silly, instead we put a call to rcu_pending() in
rcu_check_callbacks(), and then make the outside calls be to
rcu_check_callbacks(). This cuts down on the code a bit and
also gives the compiler a better chance of optimizing.
