nftables: Fix list of sets by family

Fix the result of command line 'nft list sets FAMILY'. It shows the
following error message:

"Error: syntax error, unexpected end of file, expecting string"

Now, it is possible shows right this information:

$ sudo nft -nna list sets ip
        set set_test {
                type ipv4_address
                elements = { 192.168.3.45, 192.168.3.43, 192.168.3.42, 192.168.3.4}
       	}
	set set_test2 {
                type ipv4_address
                elements = { 192.168.3.43, 192.168.3.42, 192.168.3.4}
       	}
	set set0 {
                type ipv4_address
                flags constant
                elements = { 127.0.0.12, 12.11.11.11}
       	}
