pgsql: Fix relcache invalidation when relfilelocator is updated

Fix relcache invalidation when relfilelocator is updated

In commit af0e7deb4a, I removed a call to RelationCloseSmgr(), because
the dangling SMgrRelation was no longer an issue. However, we still
need the call when the relation's relfilelocator changes, so that the
new relfilelocator takes effect immediately.
