Subject: [TCP]: Remove superflushious skb == write_queue_tail() check
X-Git-Tag: v2.6.26-rc1~1138^2~67

[TCP]: Remove superflushious skb == write_queue_tail() check

Needed can only be more strict than what was checked by the
earlier common case check for non-tail skbs, thus
cwnd_len <= needed will never match in that case anyway.
