tcpopt: don't create exthdr expression without datatype

The reproducer crashes during concat evaluation, as the
exthdr expression lacks a datatype.

This should never happen, i->dtype must be set.

In this case the culprit is tcp option parsing, it will
wire up a non-existent template, because the "nop" option
has no length field (1 byte only).
