I disagree with this.  We put attributes that apply to all devices in
scsi_device classdev.  We're implementing a separate transport interface
here, so it really does need its own class_device, otherwise separating
it from scsi_sysfs and allowing arbitrary transport class creation will
become a real pain.

A class is supposed to represent a device interface, and the transport
class does just that for transport attributes.
