net/mlx4_en: Release TX QP when destroying TX ring 

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: ddae0349fd ('net/mlx4: Change QP allocation scheme')
