iio:ti-ads1015: fix a wrong pointer definition.

commit 522caebb2c3684f4a1d154526fb5e33f1381e92a upstream.

The call to i2c_get_clientdata(client) returns a struct iio_dev*, not
the needed struct ads1015_data*. We need here an intermediate step as
in the function: void ads1015_get_channels_config(struct i2c_client *client).
