[PULL 11/31] hw/i386/amd_iommu: Remove intermediate AMDVIState::devid field

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

From: Philippe Mathieu-Daudé <philmd@linaro.org>

AMDVIState::devid is only accessed by build_amd_iommu() which
has access to the PCIDevice state. Directly get the property
calling object_property_get_int() there.
