virtualmachinestoragemigration keeps in WaitForLiveMigrationToComplete phase even the migration is finished

CNV-v4.21.0.rhel9-83

Always

1. Create a VM 
2. Create a VirtualMachineStorageMigrationPlan
3. Create a VirtualMachineStorageMigration to start the migration
4. Monitor the virt-laucher pods, DV/PVC,  VirtualMachineStorageMigrationPlan and VirtualMachineStorageMigration

We can see the new virt-laucher pod running and old one is completed. VM is pointing to the new disk
