[PATCH v3] graph: remove the useless duplicate name check

[Haiyue Wang <haiyue.wang@intel.com>]

The node clone API parameter 'name' is the new node's postfix name, not
the final node name, so it makes no sense to check it. And the new name
will be checked duplicate when calling API '__rte_node_register'.

And update the test case to call clone API twice to check the real name
duplicate.

v3: No need to define another node id var.
v2: update the test case.
