net/mlx5: Disable roce at HCA level
Currently, when a user disables roce via the devlink param, this change
isn't passed down to the device.
If device allows disabling RoCE at device level, make use of it. This
instructs the device to skip memory allocations related to RoCE
functionality which otherwise is done by the device.
