vfio/igd: Fix incorrect error propagation in vfio_pci_igd_opregion_detect()
In vfio_pci_igd_opregion_detect(), errp will be set when the device does
not have OpRegion or is hotplugged. This errp will be propagated to
pci_qdev_realize(), which interprets it as failure, causing unexpected
termination on devices without OpRegion like SR-IOV VFs or discrete
GPUs. Fix it by not setting errp in vfio_pci_igd_opregion_detect().
This patch also checks if the device has OpRegion before hotplug status
to prevent unwanted warning messages on non-IGD devices.
Fixes: c0273e77f2d7 ("vfio/igd: Detect IGD device by OpRegion")
