Subject: [PATCH 5.15 075/846] drm/ttm: Put BO in its memory managers lru list

From: xinhui pan <xinhui.pan@....com>

commit 781050b0a3164934857c300bb0bc291e38c26b6f upstream.

After we move BO to a new memory region, we should put it to
the new memory manager's lru list regardless we unlock the resv or not.
