tipc: make resetting of links non-atomic
In order to facilitate future improvements to the locking structure, we want to make resetting and establishing of links non-atomic. I.e., the functions tipc_node_link_up() and tipc_node_link_down() should be called from outside the node lock context, and grab/release the node lock themselves. This requires that we can freeze the link state from the moment it is set to RESETTING or PEER_RESET in one lock context until it is set to RESET or ESTABLISHING in a later context. The recently introduced link FSM makes this possible, so we are now ready to introduce the above change. This commit implements this.
