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.
