    x86/EPT: also force EMT re-evaluation if pinned ranges change
    
    This was inadvertently left out of aa9114ed ("x86/EPT: force
    re-evaluation of memory type as necessary"). Note that this
    intentionally doesn't use memory_type_changed(): Changes to the pinned
    ranges are independent of IOMMU presence, which that function uses to
    determine whether to call the underlying p2m_memory_type_changed().
