      x86/vtd: fix iommu_share_p2m_table
      
      Commit 2916951c1 "mm / iommu: include need_iommu() test in
      iommu_use_hap_pt()" changed the check in iommu_share_p2m_table to use
      need_iommu(d) (as part of iommu_use_hap_pt) instead of iommu_enabled,
      which broke the check because at the point in domain construction
      where iommu_share_p2m_table is called need_iommu(d) will always return
      false.
      
      Fix this by reverting to the previous logic.
      
      While there turn the hap_enabled check into an ASSERT, since the only
      caller of iommu_share_p2m_table already performs the hap_enabled check
      before calling the function.
