[azure] Install fails when setting diskEncryptionSet under defaultMachinePlatform/controlPlane/compute without subscriptionId

Configure diskEncryptionSet as below in install-config.yaml, and not set subscriptionID as it is optional parameter.

install-config.yaml
--------------------------------
compute:
- architecture: amd64
  hyperthreading: Enabled
  name: worker
  platform:
    azure:
      encryptionAtHost: true
      osDisk:
        diskEncryptionSet:
          resourceGroup: jima07a-rg
          name: jima07a-des
  replicas: 3
controlPlane:
  architecture: amd64
  hyperthreading: Enabled
  name: master
  platform:
    azure:
      encryptionAtHost: true

    defaultMachinePlatform:
      osDisk:
        diskEncryptionSet:
          resourceGroup: jima07a-rg

Then create manifests file and create cluster, installer failed with error:
$ ./openshift-install create cluster --dir ipi --log-level debug

It works well when setting disk encryption set without subscriptionId under defalutMachinePlatform or controlPlane/compute.    

4.13.0-0.nightly-2023-03-05-104719

Always on 4.11, 4.12, 4.13

1. Prepare install-config, configure diskEncrpytionSet under defaultMchinePlatform, controlPlane and compute without subscriptionId
2. Install cluster 
3.

Cluster is installed successfully
