drm: ttm: virtio-gpu: dma-buf: Constify ttm_place structures.



ttm_place are not supposed to change at runtime. All functions
working with ttm_place provided by <drm/ttm/ttm_placement.h> work
with const ttm_place. So mark the non-const structs as const.

File size before:
   text	   data	    bss	    dec	    hex	filename
   2315	    184	      0	   2499	    9c3 drivers/gpu/drm/virtio/virtgpu_ttm.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   2347	    152	      0	   2499	    9c3 drivers/gpu/drm/virtio/virtgpu_ttm.o
