Fix up sfputil and transceiver CLI commands to display only 4 lanes worth information for QSFP+C transceivers

[aditya-nexthop]

CLI/sfputil commands display 8 lanes worth information for QSFP+C (QSFP transceivers managed by CMIS) transceivers.

This issue tracks fixing up the code to only display 4 lanes/applications.
