[PATCH 1/1] rcu: Fix build failure

[Pranith Kumar]

Hi Paul,

While running the kvm rcutorture test scripts, I encountered a build failure caused by

Commit 918179699e4a ("rcu: Don't keep timekeeping CPU tick running for non-nohz_full= CPUs")

This commit fixes the failure. This is on top of paul/rcu/dev.
