    It is better to show error stats to user when we found tree block
    spanning stripes.
    
    On a btrfs created by old version of btrfs-convert:
    Before patch:
      # btrfs scrub start -B /dev/vdh
      scrub done for 8b342d35-2904-41ab-b3cb-2f929709cf47
              scrub started at Tue Aug 25 21:19:09 2015 and finished after 00:00:00
              total bytes scrubbed: 53.54MiB with 0 errors
      # dmesg
      ...
      [  128.711434] BTRFS error (device vdh): scrub: tree block 27054080 spanning stripes, ignored. logical=27000832
