event: fix crash on child-source state modifications
Setting a child-source state to anything but SD_EVENT_OFF currently does nothing. The condition logic is flawed. Move the state update *below* the test for the previous state. Fixes a crash if you call: sd_event_source_set_enabled(source, SD_EVENT_ON); sd_event_source_unref(source); on a child-source in its own callback.
