hv: destroy IOMMU domain after vpci_cleanup()

Browse Source 
In partition mode, unassign_iommu_device() is called from vpci_cleanup(),
so when shutdown_vm() is called, unassign_iommu_device() could fail because
of "domain id mismatch" and DMAR is not cleared.

Also move destroy_ept() after the call to destroy_iommu_domain().
