SGSN: Use dummy all-zero MSISDN value in PDP Context Act on GTP
The GTP protocol specification requires us to include the MSISDN IE in
all non-secondary PDP context activations. However, when no real HLR is
used (e.g. via GSUP), we do not have the MSISDN information available
and so far simply sent a zero-length MSISDN IE in GTP. The latter is a
violation of the spec.
So to resolve this, we now send a 15-digit all-zero dummy MSISDN IE, as
described in TS 23.003.
