[FIX] mrp_subcontracting: block all components = 0 qty_done

Same issue as odoo/odoo#71068 but for subcontracting rather than a MO.

Steps to reproduce:
- create a subcontracted product w/tracked component
- create receipt with subcontracted product (don't forget to set
  "Receive From" = subcontractor
- fill in Detailed Operations with tracked component lot/sn, but Done=0
- Try to record production

Expected Result: Subcontract production is done + window closes
Actual Result: nonsensical "The quantity to produce must be positive"
               validation error

Discovered during task: 2695173

closes odoo/odoo#81649
