ceph-volume: skip virtual cdrom devices in inventory

ceph-volume: skip virtual cdrom devices in inventory
-Some hosts expose IPMI/BMC virtual media as /dev/sr0. These
devices are reported as SCSI type 5 (CD/DVD) via sysfs and
appear in inventory/orchestrator output.

-These are not real disks and cannot be used as OSD targets.

-Filter out devices with SCSI type 5 to avoid listing
virtual cdrom devices as valid OSD candidates.
