virtio-pci: Check if is_avq is NULL
[bug]
In the virtio_pci_common.c function vp_del_vqs, vp_dev->is_avq is involved
to determine whether it is admin virtqueue, but this function vp_dev->is_avq
may be empty. For installations, virtio_pci_legacy does not assign a value
to vp_dev->is_avq.
[fix]
Check whether it is vp_dev->is_avq before use.
[test]
Test with virsh Attach device
Before this patch, the following command would crash the guest system
After applying the patch, everything seems to be working fine.
