Currently when *obj is not a TYPE_DEVICE, QEMU will abort. This patch
fixes it. When *obj is not a TYPE_DEVICE, just do not add it to hotpluggable
device list.
This patch also fixes the following issue:
1. boot QEMU using cli:
$ /opt/qemu-git-arm/bin/qemu-system-x86_64 -monitor stdio -enable-kvm \
-device virtio-scsi-pci,id=scsi0
2. device_del scsi0 via hmp using tab key(first input device_del, then press
"Tab" key).
(qemu) device_del
After step 2, QEMU will abort.
(qemu) device_del hw/core/qdev.c:930:qdev_build_hotpluggable_device_list:
Object 0x5555563a2460 is not an instance of type device
