Revert "usb: gadget: uvc: Add missing call for additional setup data"
commit eb38d913c27f32f4df173791051fecf6aca34173 upstream.
This reverts commit 4fbac5206afd01b717d4bdc58793d471f3391b4b.
This commit breaks g_webcam when used with uvc-gadget [1].
The user space application (e.g. uvc-gadget) is responsible for
sending response to UVC class specific requests on control endpoint
in uvc_send_response() in uvc_v4l2.c.
The bad commit was causing a duplicate response to be sent with
incorrect response data thus causing UVC probe to fail at the host
and broken control transfer endpoint at the gadget.
