Florian Westphal 0b21edf4cc netfilter: nft_tproxy: restrict to prerouting hook
commit 18bbc32133 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: 4ed8eb6570 ("netfilter: nf_tables: Add native tproxy support")
