Description of problem:

Start a  guest with xml to set vdpa device with multiqueue( vcpu=queue size), then reboot guest output error info in /var/log/libvirt/qemu/vm1.log: 

2025-07-30T05:08:12.071155Z qemu-kvm: vhost VQ 13 ring restore failed: -1: Operation not permitted (1)
2025-07-30T05:08:12.071170Z qemu-kvm: vhost VQ 14 ring restore failed: -1: Operation not permitted (1)

Version-Release number of selected component (if applicable):
kernel-6.12.0-114.el10.x86_64

qemu-kvm-10.0.0-8.el10.x86_64

libvirt-11.5.0-1.el10.x86_64

edk2-ovmf-20250523-2.el10.noarch

Guest: rhel10.1-ovmf.qcow2  (kernel-6.12.0-114.el10.x86_64)

How reproducible:
100%

Steps to Reproduce:

1. Start a vm with vdpa interface with multiqueue(vcpu=queue size),set as below:
(the vdpa device initialized by vdpa tool was set by "vdpa dev add name vdpa0 mgmtdev pci/$pci_addr mac 52:54:00:cb:45:00 max_vqp 8")

<vcpu placement="static">8</vcpu>
...
 <interface type="vdpa">
  <mac address="52:54:00:cb:45:00"/>
  <source dev="/dev/vhost-vdpa-0"/>
  <model type="virtio"/>
  <driver queues="8"/>
  <alias name="net0"/>
  <address type="pci" domain="0x0000" bus="0x01" slot="0x00" function="0x0"/>
</interface>

2. reboot guest by virsh cmd

#virsh reboot vm1
Domain 'vm1' is being rebooted

3. check the qemu log, there should not be any error or fail

# cat /var/log/libvirt/qemu/vm1.log | egrep -i "fail|error"

Actual results:  After step2 and step3, found a fail in qemu log

2025-07-30T05:37:44.020002Z qemu-kvm: vhost VQ 14 ring restore failed: -1: Operation not permitted (1)
2025-07-30T05:37:44.020008Z qemu-kvm: vhost VQ 15 ring restore failed: -1: Operation not permitted (1)

Expected results:
qemu no error info output

Additional info:
1)Network card on host: Ethernet controller: Mellanox Technologies MT2892 Family [ConnectX-6 Dx]
2) Not reproduce this bug with single queue

<interface type="vdpa">
  <mac address="52:54:00:cb:45:00"/>
  <source dev="/dev/vhost-vdpa-0"/>
