[pve-devel] [PATCH qemu-server] update disk config: consider recorded fleecing images

[Fiona Ebner <f.ebner@proxmox.com>]

Otherwise, a rescan operation would add fleecing images as unused
disks, even if they are already recorded in the special 'fleecing'
section.

Usually, fleecing images are cleaned up directly after backup, so this
is less likely to be an issue after commit 8009da73 ("fix #6317:
backup: use correct cleanup_fleecing_images helper"), but still makes
sense for future-proofing and for other edge cases where cleanup might
have failed.
