drm/vmwgfx: constify vmw_fence_ops

ArvindYadavCs · Sinclair Yeh · commit ef217b1f08fd · 2017-11-01T10:45:43.000-07:00
vmw_fence_ops are not supposed to change at runtime. Functions
"dma_fence_init" working with const vmw_fence_ops provided
by &lt;linux/dma-fence.h&gt;. So mark the non-const structs as const.
