Note that there's a "in_error_pkt" Boolean in the packet_info structure;
any dissector for a protocol in which error packets include some or all
of the packet that caused the error (ICMP, ICMPv6, OSI CLNP, etc.)
should set that flag before dissecting the error packet.

The TCP desegmentation code currently uses that to avoid including those
packets as part of TCP desegmentation; it should probably be used
elsewhere as well - the tap code might be one place to use it.
