commit b6653b3629e5b88202be3c9abc44713973f5c4b4 upstream.
tcp_fragment() might be called for skbs in the write queue.
Memory limits might have been exceeded because tcp_sendmsg() only checks limits at full skb (64KB) boundaries.
Therefore, we need to make sure tcp_fragment() wont punish applications that might have setup very low SO_SNDBUF values.
