staging: iio: ad7606: fix improper setting of oversampling pins

The oversampling ratio is controlled using the oversampling pins,
OS [2:0] with OS2 being the MSB control bit, and OS0 the LSB control
bit.

The gpio connected to the OS2 pin is not being set correctly, only OS0
and OS1 pins are being set. Fix the typo to allow proper control of the
oversampling pins.
