examples/ipsec-secgw: get security context from lcore conf

Browse Source 
Store security context pointer in lcore Rx queue config and
get it from there in fast path for better performance.
Currently rte_eth_dev_get_sec_ctx() which is meant to be control
path API is called per packet basis. For every call to that
API, ethdev port status is checked.
