For device mode, if PM runtime autosuspend feature enabled, the
runtime power status of dwc3 may be suspended when run dwc3_resume(),
and dwc3 gadget would not be configured in dwc3_gadget_run_stop().
It would cause gadget connected failed if USB cable has been plugged
before PM resume. So move forward pm_runtime_set_active() to fix it.
