[libata scsi] improve scsi error handling with ata_scsi_set_sense()
- change "xlat" and "fill" actors in libata-scsi so they are responsible for SCSI status and sense data when they return 1. This allows GOOD status or a specialized error to be set. - yield an error for mode sense requests for saved values [sat-r06] - remove static inlines for ata_bad_scsiop() and ata_bad_cdb() which are no longer used Signed-off-by: Douglas Gilbert <dougg@torque.net> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
