UUID for LV is either "LVM-<vg_uuid><lv_uuid>" or "LVM-<vg_uuid><lv_uuid>-<suffix>".
The code before just checked the length of the UUID based on the first
template, not the variant with suffix - so LVs with this suffix were not
processed properly.
For example a thin pool LV (as an example of an LV that contains
sub LVs where UUIDs have suffixes):
[0] fedora/~ # lsblk -s /dev/vg/lvol1
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
vg-lvol1 253:8 0 4M 0 lvm
`-vg-pool-tpool 253:6 0 116M 0 lvm
|-vg-pool_tmeta 253:2 0 4M 0 lvm
| `-sda 8:0 0 128M 0 disk
`-vg-pool_tdata 253:3 0 116M 0 lvm
`-sda 8:0 0 128M 0 disk
Before this patch (spurious warning message about device mismatch):
[0] fedora/~ # pvs
WARNING: Device mismatch detected for vg/lvol1 which is accessing /dev/mapper/vg-pool-tpool instead of (null).
