Fix maxium backlight level restored issue
The origin check for bring back max value for '0'
backlight level is ok for legacy or combo control method
as '0' mostly doesn't act in ideal lowest level. But it
breaks in using kernel control method which should provide
a reasonable backlight range.
This is tested fine on T61 with thinkpad_acpi module.
