cpufreq: remove unnecessary cpufreq_cpu_{get|put}() calls
struct cpufreq_policy is already passed as argument to some routines like: __cpufreq_driver_getavg() and so we don't really need to do cpufreq_cpu_get() before and cpufreq_cpu_put() in them to get a policy structure. Remove them. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
