fix bogus "bad offset in pack file" errors wrongly raised by gotd

Because copy_ref_delta() was forgetting to update the *outsize output
parameter, when clients sent ref-deltas gotd was miscalculating the
on-disk size of the pack file and would report "bad offset in pack file"
if an object was stored at an offset beyond the miscalculated smaller size.
