Don't try to use a unopened relation

Commit 4c9d0901 mistakenly introduced a call to
TransferPredicateLocksToHeapRelation() on an index relation that had
been closed a few lines above.  Moving up an index_open() call that's
below is enough to fix the problem.

Discovered by me while testing an unrelated patch.
