Reassign printk levels in selinux kernel code

Below is a patch which demotes many printk lines to KERN_DEBUG from
KERN_INFO.  It should help stop the spamming of logs with messages in
which users are not interested nor is there any action that users should
take.  It also promotes some KERN_INFO to KERN_ERR such as when there
are improper attempts to register/unregister security modules.

A similar patch was discussed a while back on list:
http://marc.theaimsgroup.com/?t=116656343500003&r=1&w=2
This patch addresses almost all of the issues raised.  I believe the
only advice not taken was in the demoting of messages related to
undefined permissions and classes.
