drm/xe: Don't print error about hwconfig when using execlists

This error message is only applicable for platforms using
GuC submission - to warn the user if the GuC they are using
or the platform they are running doesn't have this information
to provide to userspace about the platform. When forcing
execlist submission, which is something only used for debug,
the user is running at their own risk and should understand
the limitations of running without GuC.
