Subject: [PATCH 5.4 47/90] net/mlx5: E-switch, Destroy TSAR when fail to enable the mode

From: Parav Pandit <parav@...lanox.com>

[ Upstream commit 2b8e9c7c3fd0e31091edb1c66cc06ffe4988ca21 ]

When either esw_legacy_enable() or esw_offloads_enable() fails,
code missed to destroy the created TSAR.

Hence, add the missing call to destroy the TSAR.

Fixes: 610090ebce92 ("net/mlx5: E-switch, Initialize TSAR Qos hardware block before its user vports")
