Take a LocalDefId in expect_*item.

Items and item-likes are always HIR owners.
When trying to find such nodes, there is no ambiguity, the `LocalDefId` and the `HirId::owner` always match.
In such cases, `local_def_id_to_hir_id` does not carry any meaningful information, so we can just skip calling it altogether.
