[PATCH 3.19.y-ckt 008/251] net/mlx4_en: Release TX QP when destroying TX ring
3.19.8-ckt4 -stable review patch. If anyone has any objections, please let me
know.

From: Eran Ben Elisha
[ 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.
Fixes: ddae0349fdb7 ('net/mlx4: Change QP allocation scheme')
