[SCSI] sd: convert class code to use dev_groups
The dev_attrs field of struct class is going away soon, dev_groups should be used instead. This converts the scsi disk class code to use the correct field. It required some functions to be moved around to place the show and store functions next to each other, the old order seemed to make no sense at all.
