[PATCH] libata irq-pio: cleanup ata_qc_issue_prot()

ata_qc_issue_prot():
    - cleanup and let the PIO data out case always go through the
ata_dataout_task() codepath.
      (Previously for PIO data out case, 2 code pathes were used
        - irq case goes through ata_data_out_task() codepath.
        - polling case jumps over the HSM_ST_FIRST state and goes to
HSM_ST and ata_pio_task() directly.)

  ata_dataout_task():
    - rearrange the queue_work() code to handle the PIO data out +
polling case.
