Currenly in delba process calling ath11k_peer_rx_tid_delete() updates reo with desc invalid and add tid queue to the flush list. If station send data traffic without addba req and before tid flush, hw gives those packets as invalid desc reo error. Since we are dropping these invalid desc packets results in traffic stall. This patch fix this issue by updating the reo queue with bawindow size 1 instead of tid removal in delba process.
