sgsnemu: delete pdp context - teardown must be before NSAPI
in front of Cisco and Alcatel GGSN's, we meet the following error :
5 packets transmitted
Disconnecting PDP context #0
openggsn[24940]: gtp.c: 2417: Unexpected cause value received: 193. Packet from 172.29.5.130:2123, length: 14, content: 32 15 00 06 00 00 00 01 04 02 00 00 01 c1
it is because in the sgsnemu requests packet, the teardown field is after the NSAPI field :
