[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.
