[FIX] stock: location domain on reordering rules

The model reordering rules (stock.warehous.orderpoint) has two fields
waherouse_id and location_id. This commit will restrict the domain on
location_id depending on the warehouse set. The user can now choose only
locations child of the warehouse view location or location with no warehouse parent.
