RDMA/mlx5: Use the proper number of ports

Browse source 
The cited commit allowed the driver to operate over HCAs that have
4 physical ports. Use the number of ports of the RDMA device in the for
loop instead of using the struct size.

Fixes: 4cd14d44b1 ("net/mlx5: Support devices with more than 2 ports")
