lvm: fix reusing minion pool for os morphing and disk replication

[petrutlucian94]

We're disabling lvm udev rules as part of the backup writer setup in order to prevent the migrated volumes from being automatically mounted on the replicator vm.

The problem is that we're leaving behind an initrd lvm hook that will error out if the lvm udev rules are missing:

update-initramfs: Generating /boot/initrd.img-6.8.0-138-generic
E: /usr/share/initramfs-tools/hooks/lvm2 failed with return 1.

...
for rules in 56-lvm.rules 69-lvm.rules; do
	if   [ -e /etc/udev/rules.d/$rules ]; then
		cp -p /etc/udev/rules.d/$rules $DESTDIR/lib/udev/rules.d/
	elif [ -e /lib/udev/rules.d/$rules ]; then
		cp -p /lib/udev/rules.d/$rules $DESTDIR/lib/udev/rules.d/
	else
		exit 1
	fi
done
...

This prevents other packages from getting installed, breaking the os morphing initialization.

We'll solve it by removing the leftover lvm hook.
