IB/mlx4: Fix port query for 56Gb Ethernet links 

Report the correct speed in the port attributes when using a 56Gbps
ethernet link.  Without this change the field is incorrectly set to 10.

Fixes: a9c766bb75 ('IB/mlx4: Fix info returned when querying IBoE ports')
Fixes: 2e96691c31 ('IB: Use central enum for speed instead of hard-coded values')
