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

Fixes: a2bdf10ce9 ("platform/x86: asus-wmi: Increase FAN_CURVE_BUF_LEN to 32")
