[PATCH v2 4/6] examples/ipsec-secgw: fix lcore ID restriction

[Konstantin Ananyev]

> Currently the config option allows lcore IDs up to 255,
> irrespective of RTE_MAX_LCORES and needs to be fixed.
> 
> The patch allows config options based on DPDK config.
> 
> Fixes: d299106e8e31 ("examples/ipsec-secgw: add IPsec sample application")
