[PATCH v2] drm/i915: fix kref leak in __live_active_setup error path

[WenTao Liang]

When heap_fence_create fails, the early error path calls kfree(active)
directly instead of __live_put(active), bypassing the kref_put path that
would call i915_active_fini for proper resource teardown. This skips
cleanup of the i915_active state while the initial kref from kref_init
remains unbalanced.
