Really, no; this isn't right. The state field of a SCSI device is for
the SCSI state model. Passive might be a valid device mapper state, but
it's not a valid SCSI state. If these patches can't work except by
mucking with the SCSI state model, there's some layering problem
elsewhere that needs sorting out.
