If devm_add_action() fails we are printing the error message and
returning but we have already setup a timer. Lets now use the helper
devm_add_action_or_reset() and return and so in case of error the
cleanup function will be called by the helper to delete the timer.

We set up timer, that is correct, however the timer will not run so
there is no need to stop it.
