zhekunren c8f6c8b72d net/tcp/tcp_send: Remove work_available check when updating retransmit timer 
The condition work_available(&conn->work) && tx_unacked != 0
prevented tcp_update_retrantimer from being called when the work
queue was still busy, leaving conn->timer stale or zero on
subsequent sends. This caused the RTT estimation to compute a
false RTT (m = rto - 0 = rto), creating a positive feedback loop
that inflated the RTO to extreme values (e.g., 232 half-seconds
= ~116 seconds).

Fix: remove the work_available check so that tcp_update_retrantimer
is always called when there is unacknowledged data. The decision to
re-queue the work is handled internally by tcp_update_timer.
