[PATCH] rust: pid_namespace: update AlwaysRefCounted imports from sync::aref

[Shankari Anand]

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

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

It part of a subsystem-wise split series, as suggested in:
https://lore.kernel.org/rust-for-linux/CANiq72=NSRMV_6UxXVgkebmWmbgN4i=sfRszr-G+x3W5A4DYOg@xxxxxxxxxxxxxx/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.
