Fix for TUF laptops returning with an -ENOSPC on calling
asus_wmi_evaluate_method_buf() when fetching default curves. The TUF method
requires at least 32 bytes space.
This also moves and changes the pr_debug() in fan_curve_check_present() to
pr_warn() in fan_curve_get_factory_default() so that there is at least some
indication in logs of why it fails.
