[libata] fix PIO completion race Make sure we that completion is the final action we take; prior to this change, another CPU may have changed ap->pio_task_state before we tested it a final time. Spotted by, and original patch by Albert Lee @ IBM. Also includes a minor optimization: eliminate a ton of unnecessary queue_work() calls, simply by jumping to the beginning of the FSM function ata_pio_task().
