    drm/i915/gt: perform uc late init after probe error injection
    
    [ 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))
