update_engine: Skip post DownloadAction exclusions

Post |DownloadAction| don't have direct reference to |Payload|s held
within the |PayloadState|. Hence it's required to halt exclusions for
|Action|s post |DownloadAction|.

This is done by setting the |payload_index_| within |PayloadState| >= to
the |candidate_urls_|/|response_.packages| size.

DCHECKs added where |payload_index_| is used as usage may cause out of
bounds indexing.

This change removes the dangling reference to the last |Payload|, as
previously |NextPayload()| kept |payload_index_| pointing to the last
|Payload| within |PayloadState|.
