Since upstream QEMU 8.0, it's no longer possible to call bdrv_img_create() from a coroutine anymore, meaning a backup with the directory format would crash the QEMU instance. The feature is only exposed via the monitor and was intended to be experimental. There were no user reports about the breakage and it only was noticed during the rebase for QEMU 8.1, because other parts of the backup code needed adaptation and I decided to check the BACKUP_FORMAT_DIR case too. It should not stay in a broken state of course, but avoid the maintenance cost and just make it a removed feature for Proxmox VE 8 retroactively. Signed-off-by: Fiona Ebner <f.ebner@proxmox.com>
