staging: iio: ad7192: Fix - use the dedicated reset function avoiding dma from stack.
commit f790923f146140a261ad211e5baf75d169f16fb2 upstream.
Depends on: 691c4b95d1 ("iio: ad_sigma_delta: Implement a dedicated reset function")
SPI host drivers can use DMA to transfer data, so the buffer should be properly allocated.
Keeping it on the stack could cause an undefined behavior.
The dedicated reset function solves this issue.
