If userspace exits before calling accept() on a listener that had at least
one new connection ready, we get:
Attempt to release TCP socket in state 8
This happens because the mptcp socket gets cloned when the TCP connection
is ready, but the socket is never exposed to userspace.
The client additionally sends a DATA_FIN, which brings connection into
CLOSE_WAIT state. This in turn prevents the orphan+state reset fixup
in mptcp_sock_destruct() from doing its job.
