[FIX] sale_mrp: No delivered_qty computed with partial delivery

Steps to reproduce the bug:
- Create a consumable or storable final product A with invoicing policy
in "delivered quantity"
- Create two storable products B and C
- Create a BOM kit for A with 1 B and 1 C
- Create a SO with 5 qty of A and confirm it
- Deliver 3 B and 2 C and either on "No backorder" or "With backorder"

Bug:

The delivered_qty on the SO line is of course not automatically updated
(as in this case, a right value is not computable) but the delivered_qty
was not updatable  manually and then it was possible to invoice the SO.
