[FIX] mrp: qty_available computation of a nested bom kits asked together

This revision has a similar goal than the previous revision
62c5b8d95c1ba5634e201c0c8a3e2d91fb2305a7
but this times, it's a kit/phantom bom which is nested in another
kit/phantom bom, and their computation is asked in the same time.
