mcb: Use the actual bus passed to init and release functions

The functions mcb_bus_add_devices() and mcb_devices_unregister()
take a mcb_bus as argument that is never being used. This implies
that there is only one bus.

Do not ignore mcb_bus parameter and get the actual bus_type from
the device related to this mcb_bus.
