The lockdep_assert_held() calls added to cooling_device_stats_setup()
and cooling_device_stats_destroy() by commit 790930f4 ("thermal:
core: Introduce thermal_cooling_device_update()") trigger false-positive
lockdep reports in code paths that are not subject to race conditions
(before cooling device registration and after cooling device removal).

For this reason, remove the lockdep_assert_held() calls from both
cooling_device_stats_setup() and cooling_device_stats_destroy() and
add one to thermal_cooling_device_stats_reinit() that has to be called
under the cdev lock.
