rudp looks up the ciscosm dissector for every single packet. Make this a one
time in proto_handoff and use the dissector handle.
While at it - decode the checksum when there is one. An indicator is that the
header length has space for the checksum.
Additionally we have seen "stray bytes" after the checksum we can't explain. So
decode them as data when there are some.
