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.
