If a listening MPTCP socket has unaccepted sockets at close
time, the related msks are freed via mptcp_sock_destruct(),
which in turn does not invoke the proto->destroy() method
nor the mptcp_token_destroy() function.
Due to the above, the child msk socket is not removed from
the token container, leading to later UaF.
Address the issue explicitly removing the token even in the
above error path.
