The dissector "skips to the next" using the bad tag length so I  
thought
it better to not try to keep on dissecting.
For a fuzzed file, it'll report a bunch of bad TLVs, as it'll skip to  
the wrong offset.  The dissection will be ugly, but it shouldn't crash.
For a capture of traffic from a device that's putting out values that  
aren't 2 bytes long for those TLVs, but where the length field is  
consistent with the wrong-length value, it'll skip to the right offset.
