Subject: [PATCH 26/36] SCSI: st: 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 tape class code to use
the correct field.

James, feel free to take this through your tree, or ACK it and I can
take it through mine.
