[SCSI] correct transport class abstraction to work outside SCSI
I recently tried to construct a totally generic transport class and
found there were certain features missing from the current abstract
transport class. Most notable is that you have to hang the data on the
class_device but most of the API is framed in terms of the generic
device, not the class_device.
These changes are two fold
- Provide the class_device to all of the setup and configure APIs
- Provide and extra API to take the device and the attribute class and
return the corresponding class_device
