[PATCH] iio: as3935: Use devm_delayed_work_autocancel()

[Christophe JAILLET]

Use devm_delayed_work_autocancel() instead of hand writing it.
It saves a few lines of code.

Nice.

+CC Matt as it's his driver. As this is an obvious like for like replacement

Applied to the togreg branch of iio.git and pushed out as testing
to let the autobuilders see if we missed anything.

Thanks,

Jonathan
