[PATCH] drop EOE records from printk

[PATCH] drop EOE records from printk

[Steve Grubb]

Hi,

While we are looking at the printk issue, I see that its printk'ing the EOE
(end of event) records which is really not something that we need in syslog.
Its really intended for the realtime audit event stream handled by the audit
daemon. So, lets avoid printk'ing that record type.
