[FIX] mrp: fix _set_qty_producing

On a MO which product_id has a serial tracking, some components and 2
or more WO:
The method _set_qty_producing of a WO will call the MO _set_qty_producing
method even if no changes is made on qty_producing which can produce an
undesired aditional move line when creating the MO.

On a MO which product_id has a serial tracking and some components:
Changing the qty_producing on a MO was adding a line on the component
move.

Since the _set_qty_producing method is called when creating a WO it sets
the qty_producing of the MO to 0. As it does not make sense to have a WO
set the qty_producing of a MO to 0 we will not replicate it.
