iommu/virtio: Reverse arguments to list_add

Browse Source 
Elsewhere in the file, there is a list_for_each_entry with
&vdev->resv_regions as the second argument, suggesting that
&vdev->resv_regions is the list head.  So exchange the
arguments on the list_add call to put the list head in the
second argument.
