Warner Losh e4cc6558b3 tag_action is not used at all in ata. It's set to 1 for ordered ... transactions, but that value isn't used. It's bogusly used to report in devstat, due to a cut and paste error from SCSI. Mark it as unused in cam_fill_ataio. Reclaim the memory as a new ata_flags. In addition, tag_id and init_id are completely unused, so reclaim those as 'unused' now too. These were needlessly copied when ata was split from scsi. This allows us, in the future, to create structures that can communicate AUXILIARY regsiter to the SIMs, which cannot be done now.
