Name only physical volumes in a restricted LVM scan and keep its own reads from counting as activity

- An explicit --devices list makes LVM open every device in it, while a plain scan opens only known volumes; the list now names only LVM physical volumes, read from udev by lsblk, so no other disk is touched
- RAID, multipath and encrypted volumes follow the disks they are built on, instead of turning the whole check off
- After each pvs, lvs or vgs run, the disks it read take their counters as the new baseline, so an unused disk can become idle
