rcu: Fix comment in rcu_organize_nocb_kthreads()



It used to be that the rcuo callback-offload kthreads were spawned
in rcu_organize_nocb_kthreads(), and the comment before the "for"
loop says as much.  However, this spawning has long since moved to
the CPU-hotplug code, so this commit fixes this comment.
