When firmware does not support the fan curve WMI method,
asus_wmi_evaluate_method_buf() returns -ENODEV. Callers treat this
as non-fatal, but the pr_warn() here still fires, producing
spurious boot noise on unsupported hardware. Downgrade the message
to pr_debug().

Changes in v2:
- Downgrade the message to pr_debug() as suggested by Ilpo Järvinen.
- Link to v1: https://lore.kernel.org/r/20260503174752.26288-1-armundunelis@gmail.com
