Support stream opening with an initial max-stream-data of 0. In normal case, QC_SF_BLK_SFCTL is set when a qcs instance cannot transfer more data due to flow-control. This flag is set when transfering data from MUX to quic-conn instance. However, it's possible to define an initial value of 0 for max-stream-data. In this case, qcs instance is blocked despite QC_SF_BLK_SFCTL not set. No STREAM frame is prepared for this stream as it's not possible to emit any byte, so QC_SF_BLK_SFCTL flag is never set. This behavior should cause no harm. However, this can cause a BUG_ON() crash on qcc_io_send(). Indeed, when sending is retried, it ensures that only qcs instance waiting for a new qc_stream_buf or with QC_SF_BLK_SFCTL set is present in the send_list. To fix this, initialize qcs with 0 value for msd and QC_SF_BLK_SFCTL. The flag is removed only if transport parameter msd value is non null. This should be backported up to 2.6.
