[Qemu-devel] [PATCH v2 07/10] qom/object: add set_globals flags

["Marc-André Lureau" <marcandre.lureau@redhat.com>]

Guard against calling object_property_set_globals() for all objects,
check that the class flag set_globals is set before. No need to guard
in object_property_set_globals() anymore.

Only QDev & user-creatable objects have set_globals set at this point.
