    disk - add flag to use underlying psize
    
     * If the top (disk subsystem) psize fails, try again with the
       underlying raw device psize if the DSO_RAWPSIZE flag is set for the
       disk.
    
     * This allows for disk devices and slices without a proper disklabel to
       return a correct psize, which in turn allows the device to be used
       for swap.
    
     * Previously that behaviour was integrated with the DSO_DEVICEMAPPER
       flag.
