intel-iommu: Add domain check in domain_remove_one_dev_info
The comment in domain_remove_one_dev_info() states "No need to compare
PCI domain; it has to be the same". But for the si_domain that isn't
going to be true, as it consists of all the PCI devices that are
identity mapped thus multiple PCI domains can be in si_domain. The
code needs to validate the PCI domain too.
