RDMA/mlx5: Use correct device num_ports when modify DC 

[ Upstream commit 746aa3c8cb ]

Just like other QP types, when modify DC, the port_num should be compared
with dev->num_ports, instead of HCA_CAP.num_ports.  Otherwise Multi-port
vHCA on DC may not work.

Fixes: 776a3906b6 ("IB/mlx5: Add support for DC target QP")
