[PATCH 01/26] usb: gadget: fix few outdated comments

Fix comments in code to make them up to date.

composite: claiming endpoint is now done by setting ep->claimed flag,
not ep->driver_data.

epautoconf: usb_ep_autoconfig() and usb_ep_autoconfig_ss() return
claimed endpoint with ep->claimed flag already set.
