nfqnl_zcopy can now modify the 'from' sk_buff, so drop the const qualifier and fix build warnings like:
net/netfilter/nfnetlink_queue_core.c: In function ‘nfqnl_zcopy’: net/netfilter/nfnetlink_queue_core.c:264:15: warning: passing argument 1 of ‘skb_orphan_frags’ discards ‘const’ qualifier from pointer target type if (unlikely(skb_orphan_frags(from, GFP_ATOMIC))) {
Fixes: c5f0c0e75254 ("core, nfqueue, openvswitch: Orphan frags in skb_zerocopy and handle errors")
