drm/ttm: fix kref count mess in ttm_bo_move_to_lru_tail
Fixes the following scenario:
1. Page table bo allocated in vram and linked to man->lru.
tbo->list_kref.refcount=2
2. Page table bo is swapped out and removed from man->lru.
tbo->list_kref.refcount=1
3. Command submission from userspace. Page table bo is moved
to vram. ttm_bo_move_to_lru_tail() link it to man->lru and
don't increase the kref count.
