[PATCH 4/9] qemu: backup: Use VIR_ERR_CHECKPOINT_INCONSISTENT when starting a backup

[Peter Krempa <pkrempa@xxxxxxxxxx>]

If we don't have a consistent chain of bitmaps for the backup to proceed
we'd report VIR_ERR_INVALID_ARG error code, which makes it hard to
decide whether an incremental backup makes even sense.
