virtio_iommu: Clear IOMMUPciBus pointer cache when system reset
s->iommu_pcibus_by_bus_num is a IOMMUPciBus pointer cache indexed
by bus number, bus number may not always be a fixed value,
i.e., guest reboot to different kernel which set bus number with
different algorithm.
This could lead to endpoint binding to wrong iommu MR in
virtio_iommu_get_endpoint(), then vfio device setup wrong
mapping from other device.
Remove the memset in virtio_iommu_device_realize() to avoid
redundancy with memset in system reset.
