[ Upstream commit 88c9483faf15ada14eca82714114656893063458 ]
Currently, when driver queries PTYS to report which link speed is being
used on its RoCE ports, it does not check the case of having 400Gbps
transmitted over 8 lanes. Thus it fails to report the said speed and
instead it defaults to report 10G over 4 lanes.
Add a check for the said speed when querying PTYS and report it back
correctly when needed.
Fixes: 08e8676f1607 ("IB/mlx5: Add support for 50Gbps per lane link modes")
