Return of message handling has now changed to an enum that can
take non-negative value that is not zero in case a reply is
needed. But the code checking the variable afterwards has not
been updated, leading to success messages handling being
treated as errors.
Fixes: 4e601952cae6 ("vhost: message handling implemented as a callback array")
