[PATCH] refs: ref_iterator_peel returns boolean, rather than peel_status

From: Han-Wen Nienhuys via GitGitGadget <gitgitgadget@gmail.com>

Message-ID: <pull.1006.git.git.1618484566164.gitgitgadget@gmail.com>

From: Han-Wen Nienhuys <hanwen@google.com>

Before, the cached ref_iterator would return peel_object() output directly. This led to spurious differences in the GIT_TRACE_REFS output, depending on the ref storage backend active.
