ACPI / video: Fix use_native_backlight selection logic
Commit 751109aad583 ("ACPI / video: Change the default for
video.use_native_backlight to 1") has changed the default for
use_native_backlight from 0 to 1, but instead of changing
use_native_backlight_dmi to true, and leaving use_native_backlight_param at -1,
it has changed use_native_backlight_param to 1.
This causes acpi_video_use_native_backlight() to always think that a value was
specified through the param, making it impossible to add a dmi based quirk
to force 0 now that the default is 1.
This fixes this by restoring the use_native_backlight_param default to -1, and
instead setting the use_native_backlight_dmi default to true.
