Subject: [PATCH 53/70] cpufreq: interactive: Remove unnecessary cpu_online() check

From: Viresh Kumar <viresh.kumar@...aro.org>

Cpufreq no longer calls governor callback for offlined cpus. i.e. All
policy->cpus are guaranteed to be online. Hence we don't need explicit check to
see if cpu is online or not.
