[PATCH v6 05/23] send-pack: move REF_STATUS_REJECT_NODELETE logic a bit higher

20e8b465 (refactor ref status logic for pushing, 2010-01-08) restructured the code to set status for each ref to be pushed, but did not quite go far enough. We inspect the status set earlier by set_refs_status_for_push() and then perform yet another update to the status of a ref with an otherwise OK status to be deleted to mark it with REF_STATUS_REJECT_NODELETE when the protocol tells us never to delete.

Split the latter into a separate loop that comes before we enter the per-ref loop. This way we would have one less condition to check in the main loop.
