The device controller may update vbus status via usb_udc_vbus_handler(), which tries to connect the gadget even though gadget_bind_driver() has already called usb_udc_connect_control_locked(). This causes pullup() to be called twice. Avoid this by checking if gadget->connected is true. This also set gadget->connected as false in usb_gadget_activate() if it became connected while it was being deactivated. Otherwise, usb_gadget_connect_locked will return early and pullup() won't be called.
