[PATCH] ttm/bo: make ttm_swap_ops static

[Ben Dooks]

The ttm_swap_ops is not exported from this file, so make it static
to avoid the following sparse warning:

drivers/gpu/drm/ttm/ttm_bo.c:1202:31: warning: symbol 'ttm_swap_ops' was not declared. Should it be static?

Fixes: 10efe34dae798c652053d43 ("drm/ttm: Use the LRU walker helper for swapping")
