Florian Westphal 83ef55c428 netfilter: nft_tproxy: restrict to prerouting hook
commit 18bbc3213383a82b05383827f4b1b882e3f0a5a5 upstream.

TPROXY is only allowed from prerouting, but nft_tproxy doesn't check this.
This fixes a crash (null dereference) when using tproxy from e.g. output.

Fixes: 4ed8eb6570a4 ("netfilter: nf_tables: Add native tproxy support")
