From: Vinod Koul <vkoul@kernel.org>

commit 409543cec01a84610029d6440c480c3fdd7214fb upstream.

Commit b470e10eb43f ("spi: core: add dma_map_dev for dma device") added
dma_map_dev for _spi_map_msg() but missed to add for unmap routine,
__spi_unmap_msg(), so add it now.

Fixes: b470e10eb43f ("spi: core: add dma_map_dev for dma device")
