Igor Mammedov 943b9fc261 qdev: Fix object reference leak in case device.realize() fails ... If device doesn't have parent assined before its realize is called, device_set_realized() will implicitly set parent to '/machine/unattached'. However device_set_realized() may fail after that point at several other points leaving not realized object dangling in '/machine/unattached' and as result caller of obj = object_new() obj->ref == 1 object_property_set_bool(obj,..., true, "realized",...) obj->ref == 2 if (fail) object_unref(obj); obj->ref == 1 will get object leak instead of expected object destruction. Fix it by making device_set_realized() to cleanup after itself in case of failure. Backports commit 69382d8b3e8600b349c191394d761dcb480502cf from qemu		2018-02-25 21:00:26 -05:00
