mptcp: really cope with fastopen race

CVE-2024-26708

Description

In the Linux kernel, the following vulnerability has been resolved:

Fastopen and PM-trigger subflow shutdown can race, as reported by syzkaller.

In my first attempt to close such race, I missed the fact that the subflow status can change again before the subflow_state_change callback is invoked.

Address the issue additionally copying with all the states directly reachable from TCP_FIN_WAIT1.
