man-pages-posix: possibly a typo in sendmsg(3p)

Hi,

https://man7.org/linux/man-pages/man3/sendmsg.3p.html

In the EXAMPLES section it states a "Done." which is weird here. I suppose it
should be a "None."? A quick grep shows the whole 3p manuals (2017) only have
the one occurrence.

  ~/man-pages-posix-2017/man3p ❯ rg Done.
  sendmsg.3p
  281:Done.

It's an upstream issue. Also in:

https://pubs.opengroup.org/onlinepubs/9799919799/

I don't have an Austin group account unfortunately so could someone give a
help and file this?

Thanks!
