sctp: Tag messages that can be Nagle delayed at creation.
When we create the sctp_datamsg and fragment the user data, we know exactly if we are sending full segments or not and how they might be bundled. During this time, we can mark messages a Nagle capable or not. This makes the check at transmit time much simpler. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com>
