Subject: net/mlx5e: Apply the correct check for supporting TC esw rules split
Patch-mainline: v4.20-rc4
Git-commit: 1392f44bba22533b8dfdc6b0e73610b27c3f76cf
References: bsc#1103990 FATE#326006

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.
