gbproxy: Separate SGSN numeric namespaces

Currently the SGSN side message's TLLI are searched without checking
the originating SGSN. This leads to collisions if both SGSN use the
same P-TMSI for different MS.

With this patch, the SGSN NSEI is stored within the tlli_info and is
used in comparisons to separate the namespaces.

Note that this type of collision cannot happen with BSS numbers,
since the tlli_info are already separated and stored per (BSS) peer.
