After creating at least one graph and calling rte_node_edge_update to
add a new edge on a node which is in use in the graph, the node memory
is reallocated but the active graph still has a pointer to the freed
memory.
When destroying the graph, it causes a use-after-free error detected by
libasan:

Use malloc+memcpy and add an internal function to replace all references
to the old node memory before freeing it.
