rgwloadbalancer undefined index variable

The vrrp_instances variable is using a loop with index but the index_var
wasn't defined.
As a result, the fact task was failing on this undefined index variable.

The task includes an option with an undefined variable. The error was:
'index' is undefined

Closes: #5395
