Don't try to use a unopened relation
Commit4c9d090 mistakenly introduced a call toTransferPredicateLocksToHeapRelation() on an index relation that hadbeen closed a few lines above. Moving up an index_open() call that'sbelow is enough to fix the problem.Discovered by me while testing an unrelated patch.
