[Intel-gfx] [PATCH] drm/i915/gt: perform uc late init after probe error injection

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))
Fixes: 481d458caede ("drm/i915/guc: Add golden context to GuC ADS")
