tcp: refine memory limit test in tcp_fragment()
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.
Fixes: f070ef2ac667 ("tcp: tcp_fragment() should apply sane memory limits")
