    protocol/server: Race between server_reconfigure and server_setvolume

    During server_reconfigure we authenticate each connected clients
    against the current options. To do this authentication we store
    previous values in a dictionary during the connection establishment
    phase (server_setvolume). If the authentication fails during
    reconfigure then we will disconnect the transport.

    Here it introduce a race between server_setvolume and reconfugure.
    If a reconfigure called before doing a setvolume, the transport
    will be disconnected
