thermal/drivers/exynos: Handle devm_regulator_get_optional return value correctly 



Currently, if regulator is required in the SoC, but
devm_regulator_get_optional fails for whatever reason, the execution
will proceed without propagating the error. Meanwhile there is no
reason to output the error in case of -ENODEV.
