netfilter: replace skb_try_make_writable() by skb_ensure_writable()
skb_try_make_writable() only works on clones and uncloned packets might
have their network header in paged fragments.
nft_fwd needs to work for the ingress and egress hooks, but the egress
hook where skb->data points to the mac header, use skb_network_offset()
to include the mac header. The flowtable is fine since it already uses
the transport offset.
Fixes: d32de98ea70f ("netfilter: nft_fwd_netdev: allow to forward packets via neighbour layer")
Fixes: 7d2086871762 ("netfilter: nf_flow_table: move ipv4 offload hook code to nf_flow_table")
