[TCP]: Kill bogus comment above tcp_tso_acked(). 



Everything stated there is out of data.  tcp_trim_skb()
does adjust the available socket send buffer space and
skb->truesize now.

/* There is one downside to this scheme.  Although we keep the

 * Mucking with skb->truesize and sk->sk_wmem_alloc et al.
