Not a bug.

Unless GuC loading is specifically *disabled*, then the failure to load a file
is a significant event and must be logged even when debug is off. Otherwise
there will be no indication in the log that you're not running in the expected
mode, or why.

You'll probably remember that Daniel argued that there shouldn't even BE a
fallback, because it will result in confusion ("it unexpectedly continues to
work"). I say there *should* be, but it needs to be flagged vigorously in the
log so it's *really obvious* that your system is missing an important
component.

Remember that GuC submission is POR for now and the future; execlist mode is
already considered legacy on Gen9.

If you don't have the firmware, or don't want to use it, you must set
enable_guc_loading to 0. Any time the loader is asked to find a file and can't,
that's an error, even if we have a fallback method for submission.
