net/mlx5e: IPoIB, Don't allow CQE compression to be turned on by default

Browse Source 
mlx5e_build_nic_params will turn CQE compression on if the hardware
capability is enabled and the slow_pci_heuristic condition is detected.
As IPoIB doesn't support CQE compression, make sure to disable the
feature in the IPoIB profile init.

Please note that the feature is not exposed to the user for IPoIB
interfaces, so it can't be subsequently turned on.
