ziomon/ziorep_config: Add fcp-lun to -M option output

Browse Source 
Update the ‘ziorep_config’ utility to print FCP-LUN details
when the ‘-M’ option is used.

Now, ‘ziorep_config -M' option prints FCP LUN(fcp-lun) ID along with the
existing FCP device bus-id and WWPN. This addition helps correlate the
output with command 'multipathd -k', subcommand 'show topo' output,
aiding in better visibility and mapping of FCP devices to their respective
LUNs in multipath environments.

$ ziorep_config -t -M
