Fix for removing Scaled in nodes

[ilanh]

The scale in event was looking only for node IP address, there is also a line without an IP:

backend serv5 { .host = "10.100.130.68"; .port = "80"; .probe = {.url = "/varnish-probe.php"; .timeout = 1s; .interval = 5s; .window = 5; .threshold = 2; } } backend serv4 { .host = "10.100.130.56"; .port = "80"; .probe = {.url = "/varnish-probe.php"; .timeout = 1s; .interval = 5s; .window = 5; .threshold = 2; } } backend serv3 { .host = "10.100.130.30"; .port = "80"; .probe = {.url = "/varnish-probe.php"; .timeout = 1s; .interval = 5s; .window = 5; .threshold = 2; } } backend serv2 { .host = "10.100.131.103"; .port = "80"; .probe = {.url = "/varnish-probe.php"; .timeout = 1s; .interval = 5s; .window = 5; .threshold = 2; } } backend serv1 { .host = "10.100.130.36"; .port = "80"; .probe = {.url = "/varnish-probe.php"; .timeout = 1s; .interval = 5s; .window = 5; .threshold = 2; } }

sub vcl_init { new myclust = directors.round_robin();

myclust.add_backend(serv6); myclust.add_backend(serv5); myclust.add_backend(serv5); myclust.add_backend(serv4); myclust.add_backend(serv3); myclust.add_backend(serv2); myclust.add_backend(serv1); }

Without removing the other line the varnish would not restart (serv6 is not defiend)
