From: Geliang Tang <tanggeliang@kylinos.cn>

Set the EXIT trap for cleanup immediately after creating temporary file
variables, before init and make_file, to ensure cleanup runs on any
failure or interruption during the early setup phase.

Hi Geliang,

Thank you for your modifications, that's great!

- KVM Validation: normal (only selftest_mptcp_join): Success! ✅
- KVM Validation: debug (except selftest_mptcp_join): Unstable: 2 failed test(s): packetdrill_mp_join selftest_diag ⚠️ 
- KVM Validation: debug (only selftest_mptcp_join): Success! ✅
- KVM Validation: btf-normal (only bpftest_all): Success! ✅

Patchwork: https://patchwork.kernel.org/project/mptcp/list/?series=1097240


If there are some issues, you can reproduce them using the same environment as
the one used by the CI thanks to a docker image, e.g.:

    $ cd [kernel source code]
    $ docker run -v "${PWD}:${PWD}:rw" -w "${PWD}" --privileged --rm -it \
        --pull always mptcp/mptcp-upstream-virtme-docker:latest \
        auto-normal

For more details:

Please note that despite all the efforts that have been already done to have a
stable tests suite when executed on a public CI like here, it is possible some
reported issues are not due to your modifications. Still, do not hesitate to
help us improve that ;-)
