[FIX] stock: multi-company and multi-routes on product

- Multi-warehouse + Multi-company setup
- Create Company A with warehouse and 1-step delivery
- Create Company B with warehouse and 1-step delivery
- Switch to Company A: Set Logistics route on product category
  All/Saleable : 1-step delivery
- Switch to Company B: Set Logistics route on product category
  All/Saleable : 1-step delivery
- Switch to Company A, make sure Company B is turned-off
- Create new product and set category to All/Saleable
- Save product

Multi-company error is coming.

This is due to the field `route_from_categ_ids` which is a related, and
therefore fetched as `sudo` by default:

https://github.com/odoo/odoo/blob/f0330d92b31bdae4637ae0c26f40ee07282ab449/odoo/fields.py#L368

Actually, the field doesn't seem to be useful since it is only used in a
view.

Fixes odoo#58357
opw-2390983

closes odoo#62609
