[Intel-gfx] [PATCH] drm/i915/gsc: Fix error code in intel_gsc_uc_heci_cmd_submit_nonpriv()

[Teres Alexis, Alan Previn]

That was my bad, i could have sword i'd fixed that before the final rev. Thanks for fixing this.
nit: below function applies to MTL only which at the moment is still force-probed, so not sure if the fixes tag is significant.
