Ensure the pack index is opened before access

In this particular location of fsck the index should have already
been opened by verify_pack, which is called just before we get
here and loop through the object names.  However, just in case a
future version of that function does not use the index file we'll
double-check its open before we access the num_objects field.

Better safe now than sorry later.
