When the vhost iotlb is used along with a guest virtual iommu and the guest gets rebooted, some MISS messages may have been recorded just before the reboot and spuriously executed by the virtual iommu after the reboot. Despite the device iotlb gets re-initialized, the messages are not cleared. Fix that by calling vhost_clear_msg() at the end of vhost_init_device_iotlb().
