Subject: [PATCH 5.16 059/186] drm/amd/display: Reduce dmesg error to a debug print

From: Leo (Hanghong) Ma <hanghong.ma@....com>

commit 1d925758ba1a5d2716a847903e2fd04efcbd9862 upstream.

[Why & How]
Dmesg errors are found on dcn3.1 during reset test, but it's not
a really failure. So reduce it to a debug print.
