Due to a silent conflict (silent because we are trying to fix the CI
test that is meant to exercising these failures!) between commit
51e645b6652c ("drm/i915: Mark the GPU as wedged without error on fault
injection") and commit 8571a05a9dd0 ("drm/i915: Use GEM suspend when
aborting initialisation"), we failed to actually squash the error
message after injecting the load failure.
Rearrange the code to export i915_load_failure() for better logging of
real errors (and quiet logging of injected errors).
