Eric Dumazet 1bc1390377 tcp: refine memory limit test in tcp_fragment() ...

commit b6653b3629 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: f070ef2ac6 ("tcp: tcp_fragment() should apply sane memory limits")
