[PATCH v2] drm/ttm: Fix hardcoded LRU index in ttm_device_fini()

[Hongfu Li <hongfu.li@linux.dev>]

From: Hongfu Li <lihongfu@kylinos.cn>

When iterating all TTM_MAX_BO_PRIORITY LRU lists using loop variable i,
the list_empty() check references man->lru[0] instead of man->lru[i].
The loop therefore relies entirely on the state of priority 0 LRU
rather than checking each priority list individually.

Change hardcoded index man->lru[0] to man->lru[i] to correctly
inspect every per-priority LRU list.

Fixes: cf6c467d67d3 ("drm/ttm: add BO priorities for the LRUs")
