[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 Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
