Kevin Wolf e6af1e0854 block: Don't mark node clean after failed flush ... Commit 3ff2f67a changed bdrv_co_flush() so that no flush is issues if the image hasn't been dirtied since the last flush. This is not quite correct: The condition should be that the image hasn't been dirtied since the last _successful_ flush. This patch changes the logic accordingly. Without this fix, subsequent bdrv_co_flush() calls would return success without actually doing anything even though the image is still dirty. The difference is visible in some blkdebug test cases where error messages incorrectly disappeared after commit 3ff2f67a.
