Cunming Liang b94580d688 malloc: avoid unknown socket id
Add check for rte_socket_id(), avoid get unexpected return like (-1).
By using rte_malloc_socket(), socket id is assigned by socket_arg.
If socket_arg set to SOCKET_ID_ANY, it expects to use the socket id to which the current cores belongs.
As the thread may affinity on a cpuset, the cores in the cpuset may belongs to different NUMA nodes.
The value of _socket_id probably be SOCKET_ID_ANY(-1), the case is not expected in origin malloc_get_numa_socket().
