Instead of using local string names that we will have to keep

v2: Better invalid engine_id handling, capture_bo will not be able know

Hi,
Fi.CI.IGT didn't catch any failure, apart from intel_error_decode (which
didn't complain), I'm not sure which other tool could be using these names.
And now that there are icl patches, this will help there too.
