Yunxiang Li 70a3015683 drm/ttm: fix bulk_move corruption when adding a entry
commit 4481913607 upstream.

When the resource is the first in the bulk_move range, adding it again
(thus moving it to the tail) will corrupt the list since the first
pointer is not moved. This eventually lead to null pointer deref in
ttm_lru_bulk_move_del()
