audit: fix audit_filter_user_rules() initialization bug

From: Ingo Molnar <[email protected]>
Subject: [patch] audit: fix audit_filter_user_rules() initialization bug

gcc emits this warning:

kernel/auditfilter.c: In function 'audit_filter_user':
kernel/auditfilter.c:1611: warning: 'state' is used uninitialized in this function

i tend to agree with gcc - there are a couple of plausible exit paths from audit_filter_user_rules() where it does not set 'state', keeping the variable uninitialized. For example if a filter rule has an AUDIT_POSSIBLE action. Initialize to 'wont audit'. Fix whitespace damage too.
