Subject: [PATCH v2] rust: opp: update ARef and AlwaysRefCounted imports from sync::aref

Update call sites in `opp.rs` to import ARef and
AlwaysRefCounted from sync::aref instead of types.

This aligns with the ongoing effort to move ARef and
AlwaysRefCounted to sync.

Changelog:
v1 - v2 -> Fixed mistake in the commit message

Patch description:
It part of a subsystem-wise split series, as suggested in:
https://lore.kernel.org/rust-for-linux/CANiq72=NSRMV_6UxXVgkebmWmbgN4i=sfRszr-G+x3W5A4DYOg@mail.gmail.com/T/#u
This split series is intended to ease review and subsystem-level maintenance.

The original moving patch is here: (commit 07dad44aa9a93)
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=07dad44aa9a93b16af19e8609a10b241c352b440

Gradually the re-export from types.rs will be eliminated in the
future cycle.
