mptcp: remove MPTCP 'ifdef' in TCP SYN cookies
From: Matthieu Baerts <matthieu.baerts@tessares.net>
commit 3fff88186f047627bb128d65155f42517f8e448f upstream.
To ease the maintenance, it is often recommended to avoid having #ifdef
preprocessor conditions.
Here the section related to CONFIG_MPTCP was quite short but the next
commit needs to add more code around. It is then cleaner to move
specific MPTCP code to functions located in net/mptcp directory.
Now that mptcp_subflow_request_sock_ops structure can be static, it can
also be marked as "read only after init".
