quic: fix stream tx_fifo race condition
Type: fix There is a race condition in when receiving TX from a client application : As egress_emit writes as much data as possible to the stream, if during egress_emit the app writes to the fifo, the data will be directly passed to quicly. Then TX callback happens and triggers a scheduler update telling quilcy the stream has data to send. When the next egress_emit is called and no more data has come, we have nothing to write, we return len = 0 to quicly which breaks an assert if a loss happens later on.
