[PATCH 2/6] pack-objects: use object_id in packlist_alloc()

[Jeff King <peff@peff.net>]

The only caller of packlist_alloc() already has a "struct object_id",
and we immediately copy the hash they pass us into our own object_id.
Let's avoid the unnecessary round-trip to a raw sha1 pointer.

Just noticed since I was touching that function.

This is the second-to-last raw sha1 in pack-objects.c. The final one is
slightly tricky to get rid of, because it comes from the raw base_ref
pointer we parse out of the packfile's mmap. I left it out of this
series, but I wouldn't mind if somebody wants to take a stab at it.
