[PATCH V2 09/17] usb: gadget: set correct usb_configuration for os_desc_config

[peng.fan at nxp.com]

From: Jun Li <jun.li at nxp.com>

The current way to set cdev->os_desc_config is wrong if user restart
fastboot, as the old config is not used anymore and new allocated
usb_configuration will be used, so set the os_desc_config while
usb_add_config.
