upload-pack: drop lookup-before-parse optimization

When we receive a "have" line from the client, we want to
load the object pointed to by the sha1. However, we are
careful to do:

o = lookup_object(sha1);
if (!o || !o->parsed)
o = parse_object(sha1);

to avoid loading the object from disk if we have already
seen it.  However, since ccdc603 (parse_object: try internal
cache before reading object db), parse_object already does
this optimization internally. We can just call parse_object
directly.
