Describe the bug

A clear and concise description of what the bug is.

Creating a limitation is successful then I delete the rule with the id and want afterwards create a rule again fails with following output:
tcset p2p4 --rate 480000000bps --direction incoming
[WARNING] failed to add ip link: ip link already exists. try to execute with:
(a) --overwrite option if you want to overwrite the existing rule.
(b) --add option if you want to add a new rule in addition to the existing rules.
(c) --change option if you want to change the existing rule parameter.

Expected behavior

A clear and concise description of what you expected to happen.

the second add command should be possible, because tcshow is showing:
{
"p2p4": {
"outgoing": {},
"incoming": {}
}
}

To Reproduce

Steps to reproduce the behavior:

1. tcset p2p4 --rate 480000000bps --direction incoming
2. tcdel p2p4 --id 800::800 --direction incoming
3. tcset p2p4 --rate 480000000bps --direction incoming
