Replace the warning to debug info to avoid the error message.

[Test]
Verified on HW with Intel wifi card, no errors after boot.

[Where problems could occur]
It may break Intel wifi driver.
Change the debug info only, it's unlikely.

The issue is on oem-5.14 only, no need for other kernel version.
