Bearer list defined as a global variable is used to store bearer instances. When tipc supports net namespace, bearers created in one namespace must be isolated with others allocated in other namespaces, which requires us that the bearer list(bearer_list) must be moved to tipc_net structure. As a result, a net namespace pointer has to be passed to functions which access the bearer list.
