rG2735c20d114f: vm_page: use ref_count for NOFREE counter
Summary

In managing freed PG_NOFREE pages, use ref_count instead of pindex for counting pages in freed PG_NOFREE blocks. No change in behavior is expected. This restores the (useful) property that the pindex field is of interest only for pages that are mapped to objects.
