usb: musb: remove schedule work called after flush

In musb_remove() cancel_delayed_work_sync(&musb->irq_work)
is called which flush the irq_work work queue.

After cancel delayed work, musb_remove() call
musb_gadget_cleanup->usb_del_gadget_udc->usb_del_gadget
->usb_gadget_remove_driver->usb_gadget_udc_stop->udc
->gadget->ops->udc_stop(udc->gadget);

Where musb_gadget_stop() call "schedule_delayed_work(&musb->irq_work, 0)”
which is already cancel/flush.

So remove the schedule_delayed_work(&musb->irq_work, 0);
from musb_gadget_stop function.
