[PATCH] platform/x86: asus-wmi: suppress -ENODEV warning in fan_curve_get_factory_default()

[Armandas Kvietkus]

When the firmware does not support the fan curve WMI method,
asus_wmi_evaluate_method_buf() returns -ENODEV. The caller
fan_curve_check_present() already handles this gracefully by
treating it as a non-error, but fan_curve_get_factory_default()
still emits a pr_warn() before returning, producing spurious
boot noise on unsupported hardware.

Suppress the warning for -ENODEV only, consistent with how
this error is handled elsewhere in asus-wmi.c.
