    drm/i915: Flush the existing fence before GGTT read/write

    Our fence management is lazy, very lazy. If the user marks an object as
    untiled, we do not immediately flush the fence but merely mark it as
    dirty. On the next use we have to remember to check and remove the fence,
    by which time we hope it is idle and we do not have to wait.

    v2: Throw away the old fence on the next ggtt_pin.
