Vladimir Sementsov-Ogievskiy 0df62f45c1 block/backup-top: fix failure path ... We can't access top after call bdrv_backup_top_drop, as it is already freed at this time. Also, no needs to unref target child by hand, it will be unrefed on bdrv_close() automatically. So, just do bdrv_backup_top_drop if append succeed and one bdrv_unref otherwise. Note, that in !appended case bdrv_unref(top) moved into drained section on source. It doesn't really matter, but just for code simplicity.
