[PATCH v2 05/18] cpufreq: CPPC: Use __free(put_cpufreq_policy) for policy reference

[Zihuan Zhang]

Replace the manual cpufreq_cpu_put() with __free(put_cpufreq_policy)
annotation for policy references. This reduces the risk of reference
counting mistakes and aligns the code with the latest kernel style.

No functional change intended.
