ACPI:Fix goto flows in thermal-sys
This patch fixes two minor bugs in thermal_sys: (a) The flow of goto's in thermal_hwmon_add_sysfs. (b) Remove the temp*_crit only if there is a get_crit_temp defined, in thermal_remove_hwmon_sysfs. Signed-off-by: Durgadoss R <durgadoss.r@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
