Subject: [PATCH 5.7 098/166] net/mlx5e: CT: Fix memory leak in cleanup

From: Eli Britstein <elibr@...lanox.com>

[ Upstream commit eb32b3f53d283e8d68b6d86c3a6ed859b24dacae ]

CT entries are deleted via a workqueue from netfilter. If removing the
module before that, the rules are cleaned by the driver itself, but the
memory entries for them are not freed. Fix that.
