I have no idea. Let's please just do simpler conversion and worry about embedding qc's into scsi_cmnds later. libata isn't a normal SCSI driver and has a rather its own thick midlayer doing the impedance matching inbetween && I really don't think there is too much benefit to be reaped from embedding qc's into scsi_cmnds.
