Subject: [PATCH] rust: miscdevice: update ARef import to sync::aref

Update the import of `ARef` in misc_device sample to use
`sync::aref` instead of `types`.

This is part of the ongoing effort to move `ARef` and
`AlwaysRefCounted` to the `sync` module for better modularity
and type organization.

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.
