mptcp: fix warn at shutdown time for unaccepted msk sockets
With commit b93df08ccda3 ("mptcp: explicitly track the fully
established status"), the status of unaccepted mptcp closed in
mptcp_sock_destruct() changes from TCP_SYN_RECV to TCP_ESTABLISHED.
As a result mptcp_sock_destruct() does not perform the proper
cleanup and inet_sock_destruct() will later emit a warn.
Address the issue updating the condition tested in mptcp_sock_destruct().
Also update the related comment.
Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/66
