Int 78 Fn 15  - Targa.dev - Finish Data Transfer (dma)                     [d]

   AH = 15h

Return: AH = SCSI status byte
   CF clear if successful
       AL = SCSI message byte
   CF set on error
       AL = error code (see AH=00h)

Note:  if AH=06h was previously called to set the early return mode, this
     function finishes a command AH=13h or AH=14h which returned before
     the last DMA transfer was finished
