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).
