staging:iio:tsl2x7x: Fix client data inconsistency

In probe the I2C client data is set to the iio_dev struct in probe(), but
assumed to be the tsl2X7X_chip struct in remove(). Fix this by reading the
client data back as iio_dev as well.

The issue has been discovered using the following coccinelle patch:

// <smpl>
@r1@
type T;
T data;
expression dev;
@@
(
i2c_set_clientdata(dev, (void *)data)
|
i2c_set_clientdata(dev, data)
)

@r2@
type r1.T;
T data;
position p;
expression dev;
@@
data = i2c_get_clientdata@p(dev)

@depends on r1@
position p != r2.p;
expression dev;
identifier data;
@@
*data = i2c_get_clientdata@p(dev)
// </smpl>
