[dpdk-dev] [PATCH v2 9/9] examples/l3fwd-power: fix not stop and close device

[Jianfeng Tan]

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")
