StringOutputVisitor crashes when it visits a struct because ->start_struct() is NULL. Show "<omitted>" instead of crashing. This is necessary because the virtio-blk-pci iothread-vq-mapping parameter that I'd like to introduce soon is a list of IOThreadMapping structs. This patch is a quick fix to solve the crash, but the long-term solution is replacing StringOutputVisitor with something that can handle the full gamut of values in QEMU.
