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.
