[dpdk-dev] [PATCH v8 14/19] eal: set _lcore_id and _socket_id to (-1) by default

[Cunming Liang]

For those none EAL thread, *_lcore_id* shall always be LCORE_ID_ANY.
The libraries using *_lcore_id* as index need to take care.
*_socket_id* always be SOCKET_ID_ANY unitl the thread changes the affinity
by rte_thread_set_affinity()
