vfio-container-base: Introduce vfio_container_get_iova_ranges() helper
Introduce vfio_container_get_iova_ranges() to retrieve the usable
IOVA regions of the base container and use it in the Host IOMMU
device implementations of get_iova_ranges() callback.
We also fix a UAF bug as the list was shallow copied while
g_list_free_full() was used both on the single call site, in
virtio_iommu_set_iommu_device() but also in
vfio_container_instance_finalize(). Instead use g_list_copy_deep.
Fixes: cf2647a76e ("virtio-iommu: Compute host reserved regions")
