ipe: fix use-after-free when auditing a newly loaded policy

Browse source

new_policy() audits the policy after ipe_new_policyfs_node() publishes it
and drops the new directory's inode lock. A concurrent delete can free
the policy while ipe_audit_policy_load() is still using it.

Audit the successful load under that lock.
