Subject: [PATCH] drm/radeon: remove unused variable rbo

gcc with W=1 reports this error
drivers/gpu/drm/radeon/radeon_ttm.c:201:27: error:
variable ‘rbo’ set but not used [-Werror=unused-but-set-variable]
201 | struct radeon_bo *rbo;
| ^~~

rbo use was removed with
commit f87c1f0b7b79 ("drm/ttm: prevent moving of pinned BOs")
Since the variable is not used, remove it.
