Description of problem:

During cluster installation if the host systems had multiple dual-stack interfaces configured via install-config.yaml, the installation will fail. Notably, when a single-stack ipv4 installation is attempted with multiple interfaces it is successful. Additionally, when a dual-stack installation is attempted with only a single interface it is successful.

Version-Release number of selected component (if applicable):

Reproduced on 4.12.1 and 4.12.7

How reproducible:

100%

Steps to Reproduce:

1. Assign an IPv4 and an IPv6 address to both the apiVIPs and ingressVIPs parameters in the install-config.yaml
2. Configure all hosts with at least two interfaces in the install-config.yaml
3. Assign an IPv4 and an IPv6 address to each interface in the install-config.yaml
4. Begin cluster installation and wait for failure
