Subject: net: skb_needs_check() accepts CHECKSUM_NONE for tx

From: Eric Dumazet <[email protected]>

commit 6e7bc478c9a006c701c14476ec9d389a484b4864 upstream.

My recent change missed fact that UFO would perform a complete UDP checksum before segmenting in frags.

In this case skb->ip_summed is set to CHECKSUM_NONE.

We need to add this valid case to skb_needs_check()
