Upgrading libvirt from 9.1.0 to 9.2.0 breaks creating a new internal snapshot

Software environment

• Operating system: Manjaro or any Arch based distros
• Architecture: x86
• kernel version: 6.2
• libvirt version: 9.2.0

Description of problem

Upgrading libvirt from 9.1.0 to 9.2.0 loses the ability to create a new internal snapshot.

Steps to reproduce

1. Any offline VM image qcow2 including UEFI has no issue with creating a new internal snapshot when using old libvirt 9.1.0
2. Upgrading libvirt to 9.2.0, then reboot.
3. Try to create a new internal snapshot of this offline VM image in Virt-manager or using the command line

$ sudo virsh snapshot-create-as --domain <Domain-name>

4. Get the error message:

Error creating snapshot: Operation not supported: internal snapshots of a VM with pflash based firmware are not supported

I downgraded back to libvirt 9.1.0, then reboot. This issue is fixed.
