drm/i915/huc: silence injected failure in the load via GSC path

If we can't load the HuC due to an injected failure, we don't want
to throw and error and trip CI. Using the gt_probe_error macro for
logging ensure that the error is only printed if it wasn't explicitly
injected.

v2: keep the line to less than 100 characters (checkpatch).
