    UBUNTU: SAUCE: iwlwifi: disable 6-7 GHz channels

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.

This bug is awaiting verification that the linux-oem-5.14/5.14.0-1035.38 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
