Based on the error reported by devtools/check-git-log.sh
Title better be: examples/vhost: fix floating point exception when no VMDq
>
> If the VMDQ limits is 0, a divide-by-zero error occurs.
> This patch replaces throwing a floating point exception with
> a normal error message.
Pls add fix and cc-stable tag.
