gb: Use the NS-VCI to find an existing NS-VC
Currently when a NS-RESET is recevied over a link that has not yet
been associated with a NS-VC, the NSEI is used to find an existing
NS-VC. If one is found, the reset procedure is initiated.
This behaviour is not conformant with 3GPP TS 08.16 (see chapter
4.2.3) which allows to use several NS-VC between two endpoints in
parallel.
The patch changes the implementation to use the NSVCI instead
of the NSEI to search for an existing NS-VC object.
