In case multiple nodeselectors are specified in ingress_nginx_nodeselector, the generated daemonset yaml template for nginx is invalid due to missing indentation starting with the second nodeselector

When stopping at the check of "Stop if ip var does not match local ips"
the error message is like:

  fatal: [single-k8s]: FAILED! => {
      "assertion": "ip in ansible_all_ipv4_addresses",
      "changed": false,
      "evaluated_to": false,
      "msg": "Assertion failed"
  }

That doesn't contain actual IP addresses and it is difficult to understand
what was wrong. This adds the error message which contain actual IP addresses
to investigate the issue if happens.
