PCAP file containing two packets that are not handled correctly

Build Information:

--
There are two bugs in the packet-nsip dissector both related to handling
NS-STATUS messages that contain a PDU as information element.

1. The offset is not updated correctly. This results in showing a BVCI info
element, that is not there.

2. The packet description is derived from the last PDU parsed, which is the
embedded PDU in this case. Thus the packet is described with the wrong PDU type
(e.g. NS-ALIVE instead of NS-STATUS).
