drm/ttm/tests: fix lru_count ASSERT

On pool init we should expect the lru_count for each node to be zeroed
as per __list_lru_init -> init_one_lru, but here we are asserting the
opposite.

Currently our CI is blowing up with:

10:23:33] # ttm_device_init_pools: ASSERTION FAILED at drivers/gpu/drm/ttm/tests/ttm_device_test.c:178
[10:23:33] Expected !list_lru_count(&pt.pages) to be false, but is true
[10:23:33] [FAILED] DMA allocations, DMA32 required
[10:23:33] [PASSED] No DMA allocations, DMA32 required
[10:23:33]     # ttm_device_init_pools: ASSERTION FAILED at drivers/gpu/drm/ttm/tests/ttm_device_test.c:178
[10:23:33]     Expected !list_lru_count(&pt.pages) to be false, but is true

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