[ Upstream commit 150784f9285e656373cf3953ef4a7663f1e1a0f2 ]
Probe pseudo errors should be injected only in places where real errors can be encountered, otherwise unwinding code can be broken. Placing intel_uc_init_late before i915_inject_probe_error violated this rule, resulting in following bug: __intel_gt_disable:655 GEM_BUG_ON(intel_gt_pm_is_awake(gt))
