Seems some malformed OPC UA traffic causes wireshark to "freeze",
though it recovers after a few minutes.


---------- Forwarded message ----------
Wireshark gets freezed for about two minutes when trying to decode a
malformed packet of OPCUA Service CallRequest.

There are two malformed CallRequest packets in the pcap, in which
the latter one cause the issue.

To reproduce:
 1. Load the pcap file
 2. Open "Decode as ..." dialog, select Transport source(12001) or
destination(12001) as "opcua", and press OK
 3. Wireshark gets freezed at the dialog for about 2 minutes, and then
show the packets as OpcUa.
