thermal/hwmon: Add error information printing for devm_thermal_add_hwmon_sysfs()
Ensure that all error handling branches print error information. In this
way, when this function fails, the upper-layer functions can directly
return an error code without missing debugging information. Otherwise,
the error message will be printed redundantly or missing.
