staging: iio: adc: ad7280a: handle error from __ad7280_read32()

[ Upstream commit 0559ef7fde67bc6c83c6eb6329dbd6649528263e ]

Inside __ad7280_read32(), the spi_sync_transfer() can fail with negative
error code. This change will ensure that this error is being passed up
in the call stack, so it can be handled.
