thermal: cpu_cooling: Remove usage of devm functions
In the function cpufreq_get_requested_power, the memory allocated for load_cpu is live within the function only. And after the allocation it is immediately freed with devm_kfree. There is no need to allocate memory for load_cpu with devm function so replace devm_kcalloc with kcalloc and devm_kfree with kfree.
