Jonathan Cameron 245e319019 iio: temp: maxim-thermocouple: Fix potential lack of DMA safe buffer. ...

[ Upstream commit f79aeb6c63 ]

The trick of using __aligned(IIO_DMA_MINALIGN) ensures that there is
no overlap between buffers used for DMA and those used for driver
state storage that are before the marking. It doesn't ensure
anything above state variables found after the marking. Hence
move this particular bit of state earlier in the structure.
