Subject: [net 3/9] net/mlx5: DR, Enable counter on non-fwd-dest objects

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

The current code handles only counters that attached to dest, we still
have the cases where we have counter on non-dest, like over drop etc.

Fixes: 6a48faeeca10 ("net/mlx5: Add direct rule fs_cmd implementation")
