  [libata] clean up taskfile submission to hardware
  
  When writing taskfile (an ATA command) to the controller, the exact
  setup of the taskfile is dependent on the taskfile "protocol":
  PIO, PIO Multiple, DMA, Non-data, etc.
  
  So, we separate out the submission of the taskfile to hardware into
  a separate function ata_qc_issue_prot(), which will later be the
  home for more code.
  
  Also, remove some dead code (#if 0'd).
