[Intel-gfx] [PATCH] drm/i915: Purge i915_gem_object_is_dead()

[Chris Wilson]

i915_gem_object_is_dead() was a temporary lockdep aide whilst
transitioning to a new locking structure for obj->mm. Since commit
1233e2db199d ("drm/i915: Move object backing storage manipulation to its
own locking") it is now unused and should be removed.
