Currently in udc_stop, if vbus_active flag is true, all USB activities will be stopped, but vbus_active flag is still left to be true, this causes issue, when afterwards driver tries to connect gadget device to host, But due to the uncleared vbus_active, some necessary setup steps are skipped.
This patch clears vbus_active flag in udc_stop callback.
