devm-helpers: Fix devm_delayed_work_autocancel() kerneldoc

The kerneldoc for devm_delayed_work_autocancel() contains invalid
parameter description.

Fix the parameter description. And while at it - make it more obvous that
this function operates on delayed_work. That helps differentiating with
resource-managed INIT_WORK description (which should follow in near future)

Fixes: 0341ce54 ("workqueue: Add resource managed version of delayed work init")
