Revert "net/mlx5e: Fail attempt to offload e-switch TC flows"

hulk inclusion
category: bugfix
bugzilla: 6105
CVE: NA

-------------------------------------------------

Patch "net/mlx5e: Fail attempt to offload e-switch TC flows"
depends on another patch "net/mlx5e: Use dedicated uplink
vport netdev representor", the depended patch isn't a bugfix
and it has too many conflicts with present code, so we'd
better revert this patch.
