Subject: selftests: xsk: cleanup veth pair at ctrl-c
Patch-mainline: v5.19-rc1
Git-commit: d41cb6c47474484c647933702e9fa8fb5054cdf2
References: jsc#PED-1377

Remove the veth pair when the tests are aborted by pressing
ctrl-c. Currently in this situation, the veth pair is left on the
system polluting the netdev space.
