Changes in v7:
- Fixed KUnit and rustfmtcheck errors reported by the 0-DAY CI Kernel Test Robot by correctly restoring the `arc_count` function and removing orphaned `#[cfg]` attributes.
- Added an explicit `depends on KUNIT` to `CONFIG_SAMPLE_RUST_WORKQUEUE` in `samples/rust/Kconfig` to prevent randconfig build failures when the sample is enabled but KUnit is disabled.
- Fixed an E0277 trait bounds compilation error for `TestDelayedWorkItem` by utilizing the `impl_has_delayed_work!` macro instead of a manual unsafe implementation.

rust: workqueue: add safe cancellation and status methods
Changes in v6:
- Refactored rust_helper_init_delayed_work to ensure robust, single-pass initialization
using standard kernel macros, avoiding redundant lockdep and timer setup.
- Simplified impl_has_delayed_work! macro by using direct pointer casting for
work_container_of.
- Added missing # Safety documentation blocks to reclaim methods for Arc and KBox.
- Improved documentation readability by adding vertical whitespace to all examples.
- Cleaned up link syntax by using direct inline links and removing redundant reference lists.
- Removed unused rust_helper_get_dwork_timer_fn C helper.
- Link to v5: https://lore.kernel.org/r/20260407-workqueue-v5-sent-v1-0...
