[PATCH RESEND v6 5/5] app/testpmd: stop forwarding in new or destroy event

[Huisong Li <lihuisong@huawei.com>]

When testpmd receives the new or destroy event, the port related
information will be updated. Testpmd must stop packet forwarding
before updating the information to avoid some serious problems.
