"PVE backup: rename incremental to use-dirty-bitmap" merged two variables (use_dirty_bitmap and incremental) into one, but they served two different purposes. Rename the original use_dirty_bitmap to "expect_only_dirty" so the new one doesn't conflict, and rework "PVE: use proxmox_backup_check_incremental" around that semantic. In practice, this had the effect that only one disk at a time would have a bitmap added, as after the first "use_dirty_bitmap" would be set to one and the rest would behave as if the QMP parameter of the same name was unset.
