[PATCH] net/mlx5: fix mlx5dr context release ordering

Wed Mar 6 07:02:07 CET 2024


Creating rules on group >0, creates a jump action on the group table.
Non template code releases the group data under shared mlx5dr free code,
And the mlx5dr context was already closed in HWS code.

Remove mlx5dr context release from hws resource release function.
