[Intel-gfx] [PATCH v2 4/7] drm/i915/uc: Don't use -EIO to report missing firmware

[Michal Wajdeczko]

-EIO has special meaning and is used when we want to allow
engine initialization to fail and mark GPU as wedged.
Missing firmware does not fit into this scenario as this is
permanent error not related to GPU condition.
