Only verify the source partition which target hash mismatch.
There's no need to go back to the first partition when target partition
hash failed, those partitions already passed target hash verification.
We should directly go ahead and verify the source partition corresponding
to the current partition which target hash doesn't match, and that should
be the only source partition we verify.
