netfilter: nf_tables: explicit nft_set_pktinfo() call from hook path
Instead of calling this function from the family specific variant, this
reduces the code size in the fast path for the netdev, bridge and inet
families. After this change, we must call nft_set_pktinfo() upfront from
the chain hook indirection.
