From: YU DAPENG <dapengx.yu@intel.com>

In interactive mode, if testpmd exit by calling rte_exit without cmdline
resource release, terminal will not echo keyboard input. So add code to
just show error message, but not exit testpmd when unexpected happens
on starting packet forwarding in interactive mode. User can type "quit"
to exit testpmd later.

Fixes: 5a8fb55c48ab ("app/testpmd: support unidirectional configuration")
