When the socket is closed, we need to call xprt_disconnect_done() in order to clean up the XPRT_WRITE_SPACE flag, and wake up the sleeping tasks. However, we also want to ensure that we don't wake them up before the socket is closed, since that would cause thundering herd issues with everyone piling up to retransmit before the TCP shutdown dance has completed. Only the task that holds XPRT_LOCKED needs to wake up early in order to allow the close to complete.
