commit-graph: fix progress of reachable commits

To display a progress line while iterating over all refs,
d335ce8f24 (commit-graph.c: show progress of finding reachable
commits, 2020-05-13) should have added a pair of
start_delayed_progress() and stop_progress() calls around a
for_each_ref() invocation.  Alas, the stop_progress() call ended up at
the wrong place, after write_commit_graph(), which does all the
commit-graph computation and writing, and has several progress lines
of its own.  Consequently, that new

  Collecting referenced commits: 123

progress line is overwritten by the first progress line shown by
write_commit_graph(), and its final "done" line is shown last, after
everything is finished:

  Expanding reachable commits in commit graph: 344786, done.
  Computing commit changed paths Bloom filters: 100% (344786/344786), done.
  Collecting referenced commits: 154, done.

Move that stop_progress() call to the right place.

While at it, drop the unnecessary 'if (data.progress)' condition
protecting the stop_progress() call, because that function is prepared
to handle a NULL progress struct.
