[PATCH] iio: dac: remove redundant pointer chip_info and spi_dev_id

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Pointers chip_info and spi_dev_id are being assigned but are never used
hence they are redundant and can be removed.

Cleans up clang warning:
warning: variable 'chip_info' set but not used [-Wunused-but-set-variable]
