platform/x86: asus-wmi: Don't load fan curves without fan
If we do not have a fan it does not make sense to load curves for it.
This removes the following warnings from the kernel log:
asus_wmi: fan_curve_get_factory_default (0x00110024) failed: -19
asus_wmi: fan_curve_get_factory_default (0x00110025) failed: -19
