[PATCH v2 1/6] rcu: fix header guard for rcu_all_qs()

[Ankur Arora <ankur.a.arora@oracle.com>]

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.
