qcow2: Flushing the caches in qcow2_close may fail
qcow2_cache_flush() may fail; if one of the caches failed to be flushed
successfully to disk in qcow2_close() the image should not be marked
clean, and we should emit a warning.
This breaks the (qcow2-specific) iotests 026, 071 and 089; change their
output accordingly.
