Fix TestIndexWriterOnError.testIOError failure. (#13436)

Pull request #13406 inadvertly broke Lucene's handling of tragic exceptions by
stopping after the first `DocValuesProducer` whose `close()` calls throws an
exception, instead of keeping calling `close()` on further producers in the
list.

This moves back to the previous behavior.

Closes #13434
