udev: do not overwrite ID_MODEL in 69-dm-lvm-metad.rules
We've been assigning this in 69-dm-lvm-metad.rules:
ENV{ID_MODEL}="LVM PV $env{ID_FS_UUID_ENC} on /dev/$name"
This was for the description to appear for each systemd device
unit representing this device, for example:
$systemctl -a | grep "LVM PV"
dev-block-252:2.device
loaded active plugged LVM PV
JhxC7B-YTgk-3jIU-5GVo-c4gV-W8t3-UUz06p on /dev/vda2 2
dev-disk-by\x2did-lvm\x2dpv\x2duuid\x2dJhxC7B\x2dYTgk\x2d3jIU\x2d5GVo\x2dc4gV\x2dW8t3\x2dUUz06p.device
loaded active plugged LVM PV JhxC7B-YTgk-3jIU-5GVo-c4gV-W8t3-UUz06p on
/dev/vda2 2
...
However, there could be an actual ID_MODEL that people are interested in
more than the fact that this is an LVM PV and so we shouldn't overwrite
the value.
Also, we already have a symlink /dev/disk/by-id/lvm-pv-uuid-<PV_UUID>
created which is then reflected as device unit (all device's symlinks
have systemd device unit representation) so we can still reach this
information in systemd unit listings even without setting the ID_MODEL.
