hwmon: (peci) Use devm_delayed_work_autocancel() to simplify code

Use devm_delayed_work_autocancel() instead of hand writing it. This is
less verbose and saves a few lines of code.

devm_delayed_work_autocancel() uses devm_add_action() instead of
devm_add_action_or_reset(). This is fine, because if the underlying memory
allocation fails, no work has been scheduled yet. So there is nothing to
undo.
