platform/x86: asus-wmi: Ignore return value when writing thermal policy
On some machines like the ASUS Vivobook S14 writing the thermal policy
returns the currently writen thermal policy instead of an error code.
Ignore the return code to avoid falsely returning an error when the
thermal policy was written successfully.
