examples/l3fwd-power: fix stop and close on signal

As it gets killed, in SIGINT signal handler, device is not stopped
and closed. In virtio's case, vector assignment in the KVM is not
deassigned.

This patch will invoke dev_stop() and dev_close() in signal handler.

Fixes: d7937e2e3d12 ("power: initial import")
