Make the reported length of the VJ-uncompressed tvbuff the reported 

length of the data in the PPP packet, not the value from the IP header,
just in case there's extra crap at the end.  (That appears to be the
case in at least one pppdump capture filel; that's probably either a bug
in the version of pppdump that produced the capture or in the pppdump
reading code, but, until we fix that, if we can, let's at least get this
right, so that the reported length of the tvbuff won't be less than the
length unless that was the case for the tvbuff handed to us.)
