iommu/vt-d: Avoid freeing virtual machine domain in free_dmar_iommu()
Virtual machine domains are created by intel_iommu_domain_init() and
should be destroyed by intel_iommu_domain_destroy(). So avoid freeing
virtual machine domain data structure in free_dmar_iommu() when
doamin->iommu_count reaches zero, otherwise it may cause invalid
memory access because the IOMMU framework still holds references
to the domain structure.
