MINOR: quic: liberate the TX stream buffer after ACK processing
The sending buffer of each stream is cleared when processing ACKs
corresponding to STREAM emitted frames. If the buffer is empty, free it
and offer it as with other dynamic buffers usage.
This should reduce memory consumption as before an opened stream
confiscate a buffer during its whole lifetime even if there is no more
data to transmit.
