[PATCH tip/core/rcu 2/6] rcu: Make rcu_is_cpu_rrupt_from_idle helper functions static

From: Josh Triplett <josh@joshtriplett.org>

Both rcutiny and rcutree define a helper function named
rcu_is_cpu_rrupt_from_idle(), each used exactly once, later in the
same file. This commit therefore declares these helper functions static.
