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.
