The I/O region used by this driver is always requested using
comedi_request_region(). The devpriv->io union is only used by
the common code shared by the legacy and PCI drivers.
Use the new comedi_legacy_detach() helper in the (*detach) to
release the I/O region requested by this driver. That function
will handle the proper sanity checking before releasing the
resource.
