[FIX] mrp: float division by zero

Cause

	When kit BOM line quantity is equal to zero in a sale order, it raise error
	because trying to divide bom_line_data['qty'] / bom_line_data['original_qty']
	when computing kit quantities.

Solution

	As BoMs allow components with 0 qty, a.k.a. optionnal components,
	we simply skip those to avoid a division by zero.
