This changes the argument for the interrupt handler to be the IIO device
instead of the state-struct.
Since there will be some changes to how iio_priv_to_dev() is implemented,
it could be that the helper becomes a bit slower, as it will be hidden away
in the IIO core.
The iio_priv() call will still be fast enough, as it will return a void
pointer from the public IIO device structure. So it's better to switch the
order.
