[PATCH 4/7] rust: fs: update ARef and AlwaysRefCounted imports from sync::aref

[Shankari Anand <shankari.ak0208@gmail.com>]

Update call sites in the fs subsystem to import `ARef` and
`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@mail.gmail.com/T/#u
This split series is intended to ease review and subsystem-level maintenance.

The original moving patch is here:
https://lore.kernel.org/rust-for-linux/20250625111133.698481-1-shankari.ak0208@gmail.com/

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