In vu_message_write() we use sendmsg() to send the message header,
then a write() to send the payload.
If sendmsg() fails we should avoid sending the payload, since we
were unable to send the header.
Discovered before fixing the issue with the previous patch, where
sendmsg() failed on macOS due to wrong parameters, but the frontend
still sent the payload which the backend incorrectly interpreted
as a wrong header.
