Subject: [PATCH 5.4 161/165] net/mlx5: DR, Init lists that are used in rules member

From: Erez Shitrit <erezsh@...lanox.com>

[ Upstream commit df55c5586e5185f890192a6802dc5b46fddd3606 ]

Whenever adding new member of rule object we attach it to 2 lists,
These 2 lists should be initialized first.

Fixes: 41d07074154c ("net/mlx5: DR, Expose steering rule functionality")
