We need a method for finding the subchannel of a dasd device. Let's
modify find_dev to handle this since it mostly does what we need. Up to
this point find_dev has been specific to only virtio devices.

the control unit type is the very first thing we do with any real dasd device,
this is our most likely point of failure.
