>     drm/i915: Only wait upon the execution timeline when unlocked
>     
>     In order to walk the list of all timelines, we currently require the
>     struct_mutex. We are sometimes called prior to the struct_mutex being
>     taken by the caller (i.e !I915_WAIT_LOCKED) in which case we can only
>     trust the global execution timelines (as these are owned by the device).
>     This means in the unlocked phase we can only wait upon the currently
>     executing requests and not all queued.
