net/mlx5e: TC, Remove error message log print

The cited commit attempts to update the hw stats when dumping tc actions.
However, the driver may be called to update the stats of a police action
that may not be in hardware. In such cases the driver will fail to lookup
the police action object and will output an error message both to extack
and dmesg. The dmesg error is confusing as it may not indicate an actual
error.

Remove the dmesg error.
