In multi-warehouses, the available quantities shown on product page is not the
same one used to compute the max quantity that can be bought in the checkout.
Indeed, a sale order has a required `warehouse_id` field, and the quantity that
can be bought is computed based on that warehouse.
But if the website has no warehouse set to it (in settings), the shown quantity
on product page will be computed based on all available warehouses.
It will then show an error on payment step, if the user has selected more
quantities than there is available on the warehouse used for his order.
Considering the structure of `sale.order`, displaying the quantities in
several warehouses does not make sense.
To reproduce the issue:
1. In Settings:
- Enable 'Multi-Warehouses'
- Make sure the option Website > Inventory > Warehouse in undefined
2. Create a second warehouse WH02
3. Update the quantity of "Storage Box":
- 18 in first WH (should already be present)
- 12 in WH02
4. Edit "Storage Box":
- eCommerce > Availability: "Show inventory on website and prevent
sales if not enough stock"
5. On the eShop, go on "Storage Box"
- Note that there are 30 units available
6. Add 22 "Storage Box" to the cart
7. Process checkout
Error: When trying to pay, a Server Error is raised: "We are not able to
redirect you to the payment form. You ask for 22.0 products but only
18.0 is available." This is confusing since the available quantity on
the product page is 30
