Koichiro Den fcb32111f0 iommufd: Fix missing update of domains_itree after splitting iopt_area

commit e7250ab7ca upstream.

In iopt_area_split(), if the original iopt_area has filled a domain and is
linked to domains_itree, pages_nodes have to be properly
reinserted. Otherwise the domains_itree becomes corrupted and we will UAF.
