    sys/dev/disk/dm: Fix sanity checks for striped target [3/4]
    
    0 stripe is apparently invalid, but it's currently allowed
    and generates unusable device.
    
      # kldload dm
      # dmsetup create stripe1 --table '0 1000 striped 0 10 /dev/da3 0 /dev/da4 0'
      # dmsetup ls --tree
      stripe1 (255:504430599)
      # dmsetup deps /dev/mapper/stripe1
      0 dependencies  :
      # dmsetup status /dev/mapper/stripe1
    
      # dmsetup table /dev/mapper/stripe1
