Updating commit log as following:

"
    app/testpmd: fix memory leaks on error path

    This patch fixes the resource leak issue.

    Fixes: e63b50162aa3 ("app/testpmd: clean metering and policing commands")
    Cc: stable@dpdk.org
"

1) Updated patch title
2) Removed reference to internal coverity, since others can't access it, this
information doesn't add value


Applied to dpdk-next-net/master, thanks.
