[PATCH 08/11] platform/x86: fujitsu-laptop: ignore errors when setting backlight power

Not all Fujitsu laptops support controlling backlight power through the
FUJ02E3 ACPI device. Remove the debug message informing about a failed
attempt to set backlight power as it may be confusing and the return
value of call_fext_func() is logged anyway.
