iio: proximity: ping: pass reference to IIO device as param to ping_read()

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.

But even without that rework, this looks like it can pass the 'indio_dev'
object to ping_read() and obtain the state struct via iio_priv() which is a
preferred practice than going back-n-forth (getting the state-struct, then
using iio_priv_to_dev() to get the indio_dev object back).
