Devices created using '-device' JSON syntax don't emit DEVICE_DELETED when unplugged

Host environment

• QEMU version: QEMU emulator version 6.2.50 (v6.2.0-103-ge68034b1d6-dirty)

Emulated/Virtualized environment

• Operating system: (Windows 10 21H1, Fedora 34, etc.)
• OS/kernel version: (For POSIX guests, use uname -a.)
• Architecture: (x86, ARM, s390x, etc.)

Description of problem

Run the following sequence:

  $ ./qemu-system-x86_64 -qmp stdio  \
       -device '{"driver": "virtio-mouse-pci", "id": "dev0"}' \
       -device virtio-mouse-pci,id=dev1

{"timestamp": {"seconds": 1641385071, "microseconds": 198581}, "event": "RESET", "data": {"guest": true, "reason": "guest-reset"}}

Notice the lack of a "DEVICE_DELETED" event with path "/machine/peripheral/dev0" - the device created with JSON syntax
