vfio: Set the priority of the VFIO VM state change handler explicitly
In the VFIO VM state change handler when stopping the VM, the _RUNNING bit in device_state is cleared which makes the VFIO device stop, including no longer generating interrupts. Then we can save the pending states of all interrupts in the GIC VM state change handler (on ARM). So we have to set the priority of the VFIO VM state change handler explicitly (like virtio devices) to ensure it is called before the GIC's in saving.
