net/mlx5e: Don't wait for SQ completions on close
Instead of asking the firmware to flush the SQ (Send Queue) via asynchronous completions when moved to error, we handle SQ flush manually (mlx5e_free_tx_descs) same as we did when SQ flush got timed out or on tx_timeout. This will reduce SQs flush time and speedup interface down procedure. Moved mlx5e_free_tx_descs to the end of en_tx.c for tx critical code locality.
