Since mptcp_pm_subflow_chk_stale is removed in the "mptcp: address stall
under memory pressure" series, this patch drops it from BPF to keep the
BPF tests passing.

Based-on: <cover.1785943854.git.pabeni@redhat.com>

Thanks Geliang for the quick turn around!

Both patches LGTM!

Side note: I really think it's for the better to keep the stale subflow
logic detection out of the retrans scheduler.

Hi Geliang,

Thank you for your modifications, that's great!

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

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 ;-)
