Zoltan Kiss c5f0c0e752 core, nfqueue, openvswitch: Orphan frags in skb_zerocopy and handle errors 
commit 36d5fe6a00 upstream.

skb_zerocopy can copy elements of the frags array between skbs, but it doesn't
orphan them. Also, it doesn't handle errors, so this patch takes care of that
as well, and modify the callers accordingly. skb_tx_error() is also added to
the callers so they will signal the failed delivery towards the creator of the
skb.

[bwh: Backported to 3.13: skb_zerocopy() is new in 3.14, but was moved from a
 static function in nfnetlink_queue.  We need to patch that and its caller, but
 not openvswitch.]
