Currently, rte_eal_mp_wait_lcore() function will be called by rte_exit() as the routine below: rte_exit() -> rte_eal_cleanup() -> rte_service_finalize() -> rte_eal_mp_wait_lcore()
As rte_eal_mp_wait_lcore() is announced can only be called from main lcore, rte_exit() gets the limitation implicitly as well. Or once rte_exit() is called from a worker core, the rte_exit() procedure will get stuck in the rte_eal_mp_wait_lcore() function as the core status is still running. This commit adds the limitation to rte_exit() to make things clear.
