[PATCH v2 02/18] KVM: x86: Use __free(put_cpufreq_policy) for policy reference

[Zihuan Zhang <zhangzihuan@kylinos.cn>]

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.
