[dpdk-dev v1] examples/ipsec-secgw: fix of socket id default value

[Kai Ji]

Due to recent changes to the default device socket ID, before
being used as an index for session mempool list,
set socket ID to 0 if unknown (-1).

Fixes: 7dcd73e37965 ("drivers/bus: set device NUMA node to unknown by default")
