tcp: Remove interim 'tapside' field from connection

Browse source 
We recently introduced this field to keep track of which side of a TCP flow
is the guest/tap facing one.  Now that we generically record which pif each
side of each flow is connected to, we can easily derive that, and no longer
need to keep track of it explicitly.
