iommu/vt-d: Fix possible invalid memory access caused by free_dmar_iommu()
Static identity and virtual machine domains may be cached in
iommu->domain_ids array after corresponding IOMMUs have been removed
from domain->iommu_bmp. So we should check domain->iommu_bmp before
decreasing domain->iommu_count in function free_dmar_iommu(), otherwise
it may cause free of inuse domain data structure.
