spi: dw: Replace incorrect spi_get_chipselect with set

Commit 445164e8 ("spi: dw: Replace spi->chip_select references with
function calls") replaced direct access to spi.chip_select with
spi_*_chipselect calls but incorrectly replaced a set instance with a
get instance, replace the incorrect instance.
