Patch to ulogd_filter_IP2BIN.c

A bug in the IP2BIN filter would cause the reply_ip_daddr to be NULL when added
to MySQL.  Since it appears only MySQL uses this, it would affect the MYSQL
output plugin.  I compared IP2BIN to IP2STR and found one difference. I applied
this patch and it resolved the issue (attachment too):
