thermal/drivers/cpu_cooling: Remove pointless field
The structure cpufreq_cooling_device provides a backpointer to the thermal device but this one is used for a trace and to unregister. For the trace, we don't really need this field and the unregister function as the same pointer passed as parameter. Remove it.
