tipc: remove all enabled flags from all tipc components
When tipc module is inserted, many tipc components are initialized one by one. During the initialization period, if one of them is failed, tipc_core_stop() will be called to stop all components whatever corresponding components are created or not. To avoid to release uncreated ones, relevant components have to add necessary enabled flags indicating whether they are created or not. But in the initialization stage, if one component is unsuccessfully created, we will just destroy successfully created components before the failed component instead of all components. All enabled flags defined in components, in turn, become redundant. Additionally it's also unnecessary to identify whether table.types is NULL in tipc_nametbl_stop() because name stable has been definitely created successfully when tipc_nametbl_stop() is called.
