drm/ttm: fix unused function warning 

ttm_pool_type_count() is not used when debugfs is disabled:

drivers/gpu/drm/ttm/ttm_pool.c:243:21: error: unused function 'ttm_pool_type_count' [-Werror,-Wunused-function]
static unsigned int ttm_pool_type_count(struct ttm_pool_type *pt)

Move the definition into the #ifdef block.

Fixes: d099fc8f54 ("drm/ttm: new TT backend allocation pool v3")
