drm/i915: Downgrade device register error if injected

Commit 8f460e2c78f2 ("drm/i915: Demidlayer driver loading") which
introduced manual device registration also added a message that is
submitted on device registration failure as an error.  If that failure is
triggered by error injection test, that's an expected error, but CI still
reports it as a bug.  Fix it.
