Basically, if a file is used solely by a domain we can relabel it. However, if a file can be used by other processes (not only qemu) then we must not change its label as we would be effectively cutting of the other processes we know nothing about. In this case, /dev/hwrng might be used by some other process in the system. Also the fact that it's owned by root:root and not readable by anybody except the root user, tells me that we might not want to pass the file to any domain?
