Smack: Traverse the smack_known_list using list_for_each_entry_rcu macro
In smack_from_secattr function,"smack_known_list" is being traversed using list_for_each_entry macro, although it is a rcu protected structure. So it should be traversed using "list_for_each_entry_rcu" macro to fetch the rcu protected entry.
