usb/uvc_v4l2: cleanup test for end of loop

We're trying to test for the the end of the loop here. "format" is never NULL. We don't know what "format->fcc" is because we're past the end of the loop and I think "fmt->fmt.pix.pixelformat" comes from the user so we don't know what that is either. It works, but it's cleaner to just test to see if (i = ARRAY_SIZE(uvc_formats).
