[PATCH 1/1] thermal: int3403: Delete a check before thermal_zone_device_unregister()

The thermal_zone_device_unregister() function tests whether its argument
is NULL and then returns immediately. Thus the test around the call
is not needed.

This issue was detected by using the Coccinelle software.
