[PULL 19/22] hw/i386/x86-iommu: Fix endianness issue in x86_iommu_irq_to_msi_message()

["Michael S. Tsirkin" <mst@redhat.com>]

From: Thomas Huth <thuth@redhat.com>

The values in "msg" are assembled in host endian byte order (the other
field are also not swapped), so we must not swap the __addr_head here.
