for_each_packed_object: automatically open pack index
When for_each_packed_object is called, we call
prepare_packed_git() to make sure we have the actual list of
packs. But the latter does not actually open the pack
indices, meaning that pack->nr_objects may simply be 0 if
the pack has not otherwise been used since the program
started.
In practice, this didn't come up for the current callers,
because they iterate the packed objects only after iterating
all reachable objects (so for it to matter you would have to
have a pack consisting only of unreachable objects). But it
is a dangerous and confusing interface that should be fixed
for future callers.
Note that we do not end the iteration when a pack cannot be
opened, but we do return an error. That lets you complete
the iteration even in actively-repacked repository where an
.idx file may racily go away, but it also lets callers know
that they may not have gotten the complete list (which the
current reachability-check caller does care about).
We have to tweak one of the prune tests due to the changed
return value; an earlier test creates bogus .idx files and
does not clean them up. Having to make this tweak is a good
thing; it means we will not prune in a broken repository,
and the test confirms that we do not negatively impact a
more lenient caller, count-objects.
