qcow2: Repair OFLAG_COPIED when fixing leaks
Repairing OFLAG_COPIED is usually safe because it is done after the refcounts have been repaired. Therefore, it we did not find anyone else referencing a data or L2 cluster, it makes no sense to not set OFLAG_COPIED -- and the other direction (clearing OFLAG_COPIED) is always safe, anyway, it may just induce leaks. Furthermore, if OFLAG_COPIED is actually consistent with a wrong (leaky) refcount, we will decrement the refcount with -r leaks, but OFLAG_COPIED will then be wrong. qemu-img check should not produce images that are more corrupted afterwards then they were before.
