Subject: net/mlx4_en: Release TX QP when destroying TX ring

From: Eran Ben Elisha <[email protected]>

[ Upstream commit 0eb08514fdbdcd16fd6870680cd638f203662e9d ]

TX ring QP wasn't released at mlx4_en_destroy_tx_ring. Instead, the code used the deprecated base_tx_qpn field. Move TX QP release to mlx4_en_destroy_tx_ring and remove the base_tx_qpn field.
