Thermal_Framework-Fix_crash_during_hwmon_unregister



This patch fixes the following bug:
The thermal framework creates a temp*_crit interface, only when
the get_crit_temp pointer is defined. But during the _unregister_
path, without checking for the function definition, it is trying to
remove the temp*_crit interface.
