cpufreq: qcom-cpufreq-hw: fix device node refcount leak in phandle parsing
of_parse_phandle_with_args() transfers a reference to the provider node
in out_args->np, which the caller is responsible for releasing with
of_node_put(). Neither qcom_get_related_cpus() nor
qcom_cpufreq_hw_cpu_init() ever puts args.np: they only put cpu_np, which
is a different node obtained from of_cpu_device_node_get(). The
reference is therefore leaked on every successful call, and
qcom_get_related_cpus() leaks one per present CPU.
Release args.np after the parsed index has been read in both call sites.
