usb: gadget: uvc: Prevent buffer overflow in setup handler
commit 4c92670b16727365699fe4b19ed32013bab2c107 upstream.
Setup function uvc_function_setup permits control transfer
requests with up to 64 bytes of payload (UVC_MAX_REQUEST_SIZE),
data stage handler for OUT transfer uses memcpy to copy req->actual
bytes to uvc_event->data.data array of size 60. This may result
in an overflow of 4 bytes.
