Accessed https://qaprodauth.console.redhat.com/openshift/create/osd?features=

During the creation of OSD cluster, when the user chooses the availability zone as multi-zone and enables the auto scaling option from Cluster settings > machine pool step.
By default the value of maximum nodes per zone is empty. This resulted in the text associated with the field to indicate a wrong total value.
In the current model,  it indicated the text as
"x 3 zones = 0" when the maximum node per zone is empty.
In v2 model, it is indicated the text as "x 3 zones = NaN"
This needs to change to avoid confusion.

Steps to reproduce:

1. Access https://qaprodauth.console.redhat.com/openshift/create/osd?features= {"osd-wizard-v2":"true"}
2. Choose an OSD cluster with GCP or AWS cloud options.
3. In "Cluster Settings" > "Cloud provider" page, select availability as "multi-zone"
4. Proceed to next steps and in the Machine pool step, choose the "autoscaling" option.
5. View the behavior of texts associated to maximum nodes per zone field.
6. Compare with the current wizard model and v2.

Actual results:
In the current model,  it indicates the text as  "x 3 zones = 0" when the maximum node per zone is empty.
In v2 model, it is indicated the text as "x 3 zones = NaN"

Expected results:

In v2 model, it should indicate the text as "x 3 zones = 0" when the maximum node per zone is empty.
