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.
