[FIX] stock, mrp: Fix precision overflow in forecasted report

- Fix tends to prevent precision overflow in forecasted report

Current behavior before PR:
- If there are 2 units in stock and product_uom_qty is set to 0.66 the free_stock will be equal to 1.3399999999999999

Desired behavior after PR is merged:
- If there are 2 units in stock and product_uom_qty is set to 0.66 the free_stock should be equal to 1.34
