[PATCH] make set_loginuid obey audit_enabled

Browse Source 
Hi,

I was doing some testing and noticed that when the audit system was disabled,
I was still getting messages about the loginuid being set. The following patch
makes audit_set_loginuid look at in_syscall to determine if it should create
an audit event. The loginuid will continue to be set as long as there is a context.
