drm/udl: dma-buf: Constify dma_buf_ops structures.

dma_buf_ops are not supposed to change at runtime. All functions
working with dma_buf_ops provided by <linux/dma-buf.h> work with
const dma_buf_ops. So mark the non-const structs as const.

File size before:
   text    data     bss     dec     hex filename
   2002     112       0    2114     842 drivers/gpu/drm/udl/udl_dmabuf.o

File size After adding 'const':
   text    data     bss     dec     hex filename
   2114       0       0    2114     842 drivers/gpu/drm/udl/udl_dmabuf.o
