[FIX] stock: fix _compute_outdated of stock.inventory.line

The compute `_compute_outdated` of `stock.inventory.line` didn't manage
inventory lines of different `inventory_id` because of the
ensure_one of `_get_quantities` (coming from
68518afe33).

Call `_get_quantities` by inventory and save it in a dict to be use in
the loop after.
