[PATCH] list_for_each_rcu must die: audit

["Paul E. McKenney" <paulmck@linux.vnet.ibm.com>]

All uses of list_for_each_rcu() can be profitably replaced by the
easier-to-use list_for_each_entry_rcu().  This patch makes this change
for the Audit system, in preparation for removing the list_for_each_rcu()
API entirely.  This time with well-formed SOB.
