Some musb glue drivers use gadget_driver pointer to know if any gadget drivers are loaded at some moment and base further decisions on it, like to do runtime suspend/resume or not. Right now the pointer is left alone on stop and OMAP musb glue later does wrong runtime_pm decisions because of it. Clear the gadget_driver pointer on remove, it's invalid after stop anyway.
