drm/ttm/tests: Remove checks from ttm_pool_free_no_dma_alloc

On !x86, the pool type is never initialised, and the pages are freed
back to the system.

The test broke on the list_lru rewrite, but I'm not sure how that it was
supposed to work previously. In the meantime CI is broken so reverting
for now.

Fixes: 444e2a19d7fd ("ttm/pool: port to list_lru. (v2)")
