acer-wmi: fix regression in backlight detection
Currently we disable the Acer WMI backlight device if there is no ACPI
backlight device. As a result, we end up with no backlight device at all.
We should instead disable it if there is an ACPI device, as the other
laptop drivers do. This regression was introduced in febf2d9 ("Acer-WMI:
fingers off backlight if video.ko is serving this functionality").
Each laptop driver with backlight support got a similar change around
febf2d9. The changes to the other drivers look correct; see e.g.
a598c82f for a similar but correct change. The regression is also in
2.6.28.
