iio:trigger: Use to_iio_trigger() instead of dev_get_drvdata()
Use to_iio_trigger(dev) instead of dev_get_drvdata(dev). Both will return the trigger which belongs to the device, but the the first on is a bit more lightweight. Since this is the last location where we used dev_get_drvdata() for retrieving the trigger there is no need anymore to assign the the trigger to the devices drvdata, so we can remove that as well.
