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.
