Subject: [net 07/13] net/mlx5e: Apply the correct check for supporting TC esw rules split

From: Roi Dayan <roid@...lanox.com>

The mirror and not the output count is the one denoting a split.
Fix to condition the offload attempt on the mirror count being > 0
along the firmware to have the related capability.
