Subject: [PATCH] usb: gadget: f_uvc: fix potential memory leak

If uvc->control_buf is successfuly allocated but uvc->control_req
is not, uvc->control_buf is not freed in the error recovery path.
With this patch applied uvc->control_buf is freed unconditionally;
if it happens to be NULL kfree on it is safe anyway.
