After a bad link state is detected, the sink capabilities with which the
link was originally trained could have changed: for instance another
sink got connected or the retraining was forced after the rate/lane count
got decreased (as a fallback). In these cases the retraining modeset
fails as expected also printing a debug message, so don't WARN on it.
