This fixes regression caused by commit
2d6c1ef40f3678ab47a4d14fb5dadaa486bfcda6
("char: Prevent multiple devices opening same chardev"):
-nodefaults -nographic -chardev stdio,id=stdio,mux=on,signal=off \
-mon stdio -device virtio-serial-pci \
-device virtconsole,chardev=stdio -device isa-serial,chardev=stdio
fails with:
qemu-system-x86_64: -device isa-serial,chardev=stdio: Property 'isa-serial.chardev' can't take value 'stdio', it's in use
