virtio-scsi: Set max_target=0 during vhost-scsi operation

This QEMU patch sets VirtIOSCSIConfig->max_target=0 for vhost-scsi operation
to restrict virtio-scsi LLD guest scanning to max_id=0 (a single target ID
instance) when connected to individual tcm_vhost endpoints.

This ensures that virtio-scsi LLD only attempts to scan target IDs up to
VIRTIO_SCSI_MAX_TARGET when connected via virtio-scsi-raw.
