Subject: [PATCH -next] drm/ttm/agp: Fix Wunused-variable warning

If CONFIG_AGP is not set, gcc warns:

drivers/gpu/drm/radeon/radeon_ttm.c: In function ‘radeon_ttm_tt_bind’:
drivers/gpu/drm/radeon/radeon_ttm.c:692:24: warning: unused variable ‘rdev’ [-Wunused-variable]
  struct radeon_device *rdev = radeon_get_rdev(bdev);
                        ^~~~

Move it to ifdef block to fix this.
