staging:iio:adis16260: Fix drvdata inconsistency
The SPI drvdata is set to adis16260_state struct in probe(), but assumed to be
the iio_dev struct in remove(). Fix this by setting it to the iio_dev in
probe().
The issue has been discovered using the following coccinelle patch:
// <smpl>
@r1@
type T;
T data;
expression dev;

(
spi_set_drvdata(dev, (void *)data)

spi_set_drvdata(dev, data)

type r1.T;
T data;

data = spi_get_drvdata@p(dev)
@depends on r1@
position p != r2.p;
expression dev;
identifier data;
@@
*data = spi_get_drvdata@p(dev)
