This series fixes the nft crash recently reported by Pablo with older (< 5.6) kernels: use the NFT_SET_CONCAT flag whenever we send a set including concatenated ranges, so that kernels not supporting them will not add them altogether, and we won't crash while trying to list the malformed sets that are added as a result.
