iio: adc: ad7923: Fix buffer overflow for tx_buf and ring_xfer

Browse source

commit 3a4187ec45 upstream.

The AD7923 was updated to support devices with 8 channels, but the size
of tx_buf and ring_xfer was not increased accordingly, leading to a
potential buffer overflow in ad7923_update_scan_mode().
