thermal: Replace deprecated CPU-hotplug functions.

Sebastian Andrzej Siewior · KAGA-KOKO · commit c122358ea1e5 · 2021-09-11T00:41:21.000+02:00
The functions get_online_cpus() and put_online_cpus() have been deprecated during the CPU hotplug rework. They map directly to cpus_read_lock() and cpus_read_unlock(). Replace deprecated CPU-hotplug functions with the official version. The behavior remains unchanged.
