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

[Hongfu Li]

From: Hongfu Li <lihongfu@kylinos.cn>

ttm_device_fini() iterates over all TTM_MAX_BO_PRIORITY LRU lists
using loop variable i, but list_empty() always checks man->lru[0]
instead of man->lru[i]. This means the debug message only checks
priority 0 and prints the same result four times.

Fixes: 8af8a109b34f ("drm/ttm: device naming cleanup")
