[PATCH v1] net/cpfl: fix invalid action types

[Praveen Shetty]

In case of CPFL PMD, port_representor action is used for
the local vport and represented_port action is used for
the remote port(remote port in this case is either the idpf
pf or the vf port that is being represeted by the cpfl pmd).
Any mismatch in either of the cases PMD will throw
an error.
