[PATCH v7 0/3] drm/i915: Fix VMA UAF on destroy against deactivate race

Object debugging tools were sporadically reporting illegal attempts to free a still active i915 VMA object when parking a GT believed to be idle. [161.359441] ODEBUG: free active (active state 0) object: 88811643b958 object type: i915_active hint: __i915_vma_active+0x0/0x50 [i915]
