    s3: smbd: Restart reading the incoming SMB2 fd when the send queue is drained.
    
    When the send queue grows greater than xconn->smb2.credits.max/16,
    smbd_smb2_request_next_incoming() doesn't allocate a new request in state->req.
    
    After smbd_smb2_io_handler() is called, it marks the fd not readable as
    state->req == NULL, and never marks it readable again.
    
    Fix by calling smbd_smb2_request_next_incoming() to restart
    reads inside smbd_smb2_flush_send_queue() which drains the
    send queue.
