pass correct caplen to other functions as well
In ethertype_print(), isoclns_print() and snap_print() adjust the length
arithmetics along the same lines as for ether_print() in the previous
commit. Where done, the current pointer is not greater than snapend so
that the difference (i.e. caplen) is never negative.
This does not fix a reported issue but the problem was very likely to be
there.
