Stable commit "core, nfqueue, openvswitch: Orphan frags in
skb_zerocopy and handle errors", upstream commit
36d5fe6a000790f56039afe26834265db0a3ad4c, was not correctly backported
and missed to change a const 'from' parameter to non-const. This
results in a new batch of warnings:
net/netfilter/nfnetlink_queue_core.c: In function ‘nfqnl_zcopy’:
net/netfilter/nfnetlink_queue_core.c:272:2: warning: passing argument 1 of ‘skb_orphan_frags’ discards ‘const’ qualifier from pointer target type [enabled by default]

extern void skb_tx_error(struct sk_buff *skb);
Remove const from the 'from' parameter, the same as in the upstream
commit.
As far as I can see, this leaked into 3.10, 3.12, and 3.13 already.
