Subject: [Patch] net: fix a wrong assignment in skb_split()

commit c9af6db4c11ccc6c3e7f1 (net: Fix possible wrong checksum generation)
has a suspicous piece:

	-       skb_shinfo(skb1)->gso_type = skb_shinfo(skb)->gso_type;
	-
	+       skb_shinfo(skb)->tx_flags = skb_shinfo(skb1)->tx_flags & SKBTX_SHARED_FRAG;

skb1 is the new skb, therefore should be on the left side of the assignment.
This patch fixes it.
