update_ref(): don't read old reference value before delete
If we are deleting the reference, then we don't need to read the
reference's old value. It doesn't provide any race safety, because the
value read just before the delete is no "better" than the value that
would be read under lock during the delete. And even if the reference
previously didn't exist, we can call delete_ref() on it if we don't
provide an old_sha1 value.
