Fix spinning after replace-on-reboot failure or skipped

Fix spinning after replace-on-reboot failure or skipped

If:
- extracting a file failed AND --no-replaceonreboot was used
- OR, writing the .new file for replacing on reboot failed
we don't advance to the next file in the archive, so we just sit there,
trying the same operation repeatedly.

Yes, this seems to mean that --no-replaceonreboot never worked usefully.

Also advance to next file in extract_other error case.
