examples/ipsec-secgw: fix promiscuous mode option

[ upstream commit 23d3a468c42ac8b63a36c9c4a6f01e459350f777 ]

Currently default value of promiscuous mode flag is true and
even there is command line argument to set it to true.
So it never is in non-promiscuous mode. Fix it by
changing default value to false.

Fixes: d299106 ("examples/ipsec-secgw: add IPsec sample application")
