Nuno Sa 6e4d236d9c iio: adc: ad7923: Fix buffer overflow for tx_buf and ring_xfer 
[ Upstream commit 3a4187ec45 ]

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().

Fixes: 851644a60d ("iio: adc: ad7923: Add support for the ad7908/ad7918/ad7928")
