rcu: fix header guard for rcu_all_qs()
[ Upstream commit ad6b5b73ff565e88aca7a7d1286788d80c97ba71 ]
rcu_all_qs() is defined for !CONFIG_PREEMPT_RCU but the declaration
is conditioned on CONFIG_PREEMPTION.
With CONFIG_PREEMPT_LAZY, CONFIG_PREEMPTION=y does not imply
CONFIG_PREEMPT_RCU=y.
Decouple the two.
