Fix a bug in the dissection of multiple NDS messages being sent at the same time that the dissector was attempting to desegment data spanning multiple packets. When a message was encountered during the desegmentation code the dissector would misinterpret the new message as an element in the data stream. Code was added to validate the desegmentation handle and validate which messages actually contain segmented data. svn path=/trunk/; revision=11147
