pci: call object_unparent() before free_qdev()
Start VM with 8 multiple-function block devs, hot-removing those block devs by 'device_del ...' would cause qemu abort. | (qemu) device_del virti0-0-0 | (qemu) ** |ERROR:qom/object.c:389:object_delete: assertion failed: (obj->ref == 0) It's a regression introduced by commit 57c9fafe The whole PCI slot should be removed once. Currently only one func is cleaned in pci_unplug_device(), if you try to remove a single func by monitor cmd. free_qdev() are called for all functions in slot, but unparent_delete() is only called for one function.
