[PATCH nft] src: fix obj list output when reset command

[PATCH nft] src: fix obj list output when reset command

[Jose M. Guisado Gomez]

This patch enables json output when doing a reset command.

Previously do_list_obj was called at the end of do_command_reset to
list the named object affected by the reset, this function
is for nft output only.

Listing affected objects using do_command_list ensures
output flags will be honored.

Eg: For a ruleset like

table inet x {
	counter user123 {
		packets 12 bytes 1433
	}

	counter user321 {
		packets 0 bytes 0
	}

	quota user123 {
		over 2000 bytes
	}

	quota user124 {
		over 2000 bytes
	}

	set y {
		type ipv4_addr
	}

	...
}

# nft --json reset counters | python -m json.tool
{
    "nftables": [
        {
            "metainfo": {
                "json_schema_version": 1,
                "release_name": "Capital Idea #2",
                "version": "0.9.6"
            }
        },
        {
            "counter": {
                "bytes": 0,
                "family": "inet",
                "handle": 3,
                "name": "user321",
                "packets": 0,
                "table": "x"
            }
        },
        {
            "counter": {
                "bytes": 1433,
                "family": "inet",
                "handle": 2,
                "name": "user123",
                "packets": 12,
                "table": "x"
            }
        }
    ]
}
