Subject: [PATCH] dbus-manager: fix a fatal dbus abort in
 bus_manager_message_handler()

If ListUnitFiles fails, or an OOM occurs, then dbus_message_unref()
will be called twice on "reply", causing systemd to crash.  So remove
the call to dbus_message_unref(); it is unnecessary because of
the cleanup attribute on "reply".

[zj: modified to leave one dbus_message_unref() alone, per Colin
Walters' comment.]
