app/testpmd: stop forwarding when quitting

When user quits testpmd, and there is traffic being forwarded,
that may produce a segmentation fault, due to ports being closed,
while they are still transmitting packets.

This patch prevents the issue from happening,
by stopping packet forwarding before closing the ports.
