[PATCH 2/2] drm/xe: Allow to inject error in xe_pcode_probe_early()

Allow to test if driver behaves correctly when xe_pcode_probe_early()
fails. Note that this is not sufficient for testing survivability mode
as it's still required to read the hw to check for errors, which doesn't
happen on an injected failure.
