cpufreq: CPPC: Fix possible null-ptr-deref for cppc_get_cpu_cost()
cpufreq_cpu_get_raw() may return NULL if the cpu is not in
policy->cpus cpu mask and it will cause null pointer dereference,
so check NULL for cppc_get_cpu_cost().
Fixes: 740fcdc2c20e ("cpufreq: CPPC: Register EM based on efficiency class information")
