RDMA/mlx5: Remove warn on missing representor in query_port_speed

The representor ib_device's phys_port_cnt is set to the total vport
count when the uplink vport rep loads. Individual port[i].rep entries
are populated only as each VF/SF vport rep registers. A NULL .rep for
a given port index is therefore expected while VF reps are still
loading or haven't been enabled yet.

Tools like ibstat and ibv_devinfo iterate over all ports of all RDMA
devices. Some ports may not have an eswitch representor, causing
repeated dmesg warnings when these tools run without a device argument.
This causes dmesg to be flooded with this message on every ibstat
invocation.

Remove the warning and return -ENODEV when no representor exists for
the queried port.
