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.
