for_each_reflog(): don't abort for bad references

If there is a file under "$GIT_DIR/logs" with no corresponding
reference, the old code was emitting an error message, aborting the
reflog iteration, and returning -1. But

* None of the callers was checking the exit value

* The callers all want to find all legitimate reflogs (sometimes for the
  purpose of determining object reachability!) and wouldn't benefit from
  a truncated iteration anyway.

So instead, emit an error message and skip the "broken" reflog, but
continue with the iteration.
