Why 512 words ?

Though I have queued Mark's patch to be applied, my gut feeling would lean towards a single DRQ block, rather than 512.


 	ata_altstatus(ap);
-	ata_chk_status(ap);
+	ata_drain_fifo(ap, qc);

ap->ops->cleanup();

might be wiser

If someone needs that, they can override the error handler with their own. No need for a new op.
