    unetmsg: fix reconnect loop when RX authenticates before TX
    
    When both peers connect simultaneously, the RX side can authenticate
    before the TX handshake completes. network_check_auth() was sending a
    ping on the unauthenticated TX channel, which gets rejected by the
    remote's pre-auth handler as "Auth failed", killing the connection and
    triggering an endless reconnect cycle.
    
    Check chan.auth before interacting with the TX channel. If TX auth
    hasn't completed yet, just schedule a reconnect timer - auth_data_cb
    already handles state sync when TX auth completes.
