sony-laptop: fix bogus error message display on resume 

sony_backlight_update_status returns 0 on success -1 on failure (i.e.: the
return value from acpi_callsetfunc. The return value in the resume path
was broken and thus always displaying a bogus warning about not being able
to restore the brightness level.
