Subject: [PATCH tip/core/rcu 07/12] rcu: Inline rcu_kthread_do_work() into its sole remaining caller

The rcu_kthread_do_work() function has a single-line body and only one
remaining caller.  This commit therefore saves a few lines of code by
inlining rcu_kthread_do_work() into its sole remaining caller.
