Subject: cpupower: Correct return type of cpu_power_is_cpu_online() in cpufreq-set

From: Laura Abbott <redacted>

commit c25badc9ceb612c6cc227a6fc4b0aaf678e3bcf9 upstream.

When converting to a shared library in ac5a181d065d ("cpupower: Add
cpuidle parts into library"), cpu_freq_cpu_exists() was converted to
cpupower_is_cpu_online(). cpu_req_cpu_exists() returned 0 on success and
-ENOSYS on failure whereas cpupower_is_cpu_online returns 1 on success.
Check for the correct return value in cpufreq-set.
