drm/ttm: remove set but not used variable 'driver'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/ttm/ttm_execbuf_util.c: In function 'ttm_eu_fence_buffer_objects':
drivers/gpu/drm/ttm/ttm_execbuf_util.c:190:24: warning:
 variable 'driver' set but not used [-Wunused-but-set-variable]

It not used any more after
commit f2c24b83ae90 ("drm/ttm: flip the switch, and convert to dma_fence")
