tipc: use RCU to protect media_ptr pointer Now the media_ptr pointer is protected with tipc_net_lock write lock on write side; tipc_net_lock read lock is used to read side. As the part of effort of eliminating tipc_net_lock, we decide to adjust the locking policy of media_ptr pointer protection: on write side, RTNL lock is use while on read side RCU read lock is applied.
