[syslog-ng] [PATCH] loggen: Fix a possible division by zero.

[Gergely Nagy]

In some cases where we could not send a single message, loggen tried
to divide by zero shortly before printing the statistics at the end.

This was trivially reproducible by using -R with a file that contained
invalid syslog lines.
