net/mlx4_core: Use correct variable type for mlx4_slave_cap

We've used an incorrect type for the loop counter and the mlx4_QUERY_FUNC_CAP function. The current input modifier is either a port or a boolean. Since the number of ports is always a positive value < 255, we should use u8 instead of an integer with casting.
