[PATCH 1/2] thermal/of: Add error information printing for devm_thermal_of_zone_register()

[Yangtao Li]

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.
