    drm/xe: Drop HW fence pointer to HW fence ctx
    
    The HW fence ctx objects are not ref counted rather tied to the life of
    an LRC object. HW fences reference the HW fence ctx, HW fences can
    outlive LRCs thus resulting in UAF. Drop the  HW fence pointer to HW
    fence ctx rather just store was is needed directly in HW fence.
