While hot-unplugging policy->cpu, we call cpufreq_nominate_new_policy_cpu() to nominate next owner of policy, i.e. policy->cpu. If we fail to move policy kobject under the new policy->cpu, we try to update policy->cpus with the old policy->cpu.
This would have been required in case old-cpu is removed from policy->cpus in the first place. But its not done before calling cpufreq_nominate_new_policy_cpu(), but during the POST_DEAD notification which happens quite late in the hot-unplugging path.
So, this is just some useless code hanging around, get rid of it.
