OPTIM: session: put unlikely() around the freewheeling code

The code which enables tunnel mode or TCP transfers is rarely used
and at most once per session. Putting it in an unlikely() clause
reduces the length of the hot path of process_session() which is
already quite long, and also slightly reduces its overall size.
Some measurements show a steady gain of about 0.2% thanks to this.
