[PATCH 6.6.y] Revert "selftests: mptcp: simult flows: mark 'unbalanced' tests as flaky"

[Matthieu Baerts (NGI0)]

This reverts commit 052c9f0c140c78e5d6826688b5d2f33e19db0ae7.

If the test doesn't pass, we can get this error:

  # ./simult_flows.sh: line 275: mptcp_lib_subtest_is_flaky: command not found

This patch is not needed in v6.6: it is there to mark a test as "flaky",
but the MPTCP selftests infrastructure in v6.6 doesn't support them. So
it looks better to revert this patch.

[MPTCP CI]

Hi Matthieu,

Thank you for your modifications, that's great!

Our CI did some validations and here is its report:

- KVM Validation: normal: Success! ✅
- KVM Validation: debug: Unstable: 1 failed test(s): selftest_mptcp_join 🔴
- KVM Validation: btf (only bpftest_all): Success! ✅
- Task: https://github.com/multipath-tcp/mptcp_net-next/actions/runs/10355134055

Initiator: Patchew Applier
Commits: https://github.com/multipath-tcp/mptcp_net-next/commits/cd7038c3ea89
Patchwork: https://patchwork.kernel.org/project/mptcp/list/?series=878858


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:

    https://github.com/multipath-tcp/mptcp-upstream-virtme-docker


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 ;-)
