This is redundant. In this commit, for connectionless sockets we update: - __tipc_sendmsg(), when the destination is NULL the peer existence is determined by tsk->peer.family, instead of tsk->connected. - tipc_connect(), remove set/unset of tsk->connected. Hence tsk->connected is no longer used for connectionless sockets. There is no functional change in this commit.
