[dpdk-stable] [PATCH v2] eal/service: add routine to release memory

[Vipin Varghese <vipin.varghese@intel.com>]

The routine rte_service_finalize checks if service is initialized,
if yes; releases internal memory for services and lcore states.

This routine is to be invoked at end of application termination.
