spi: spacemit: prepare both DMA descriptors before submitting

Browse source

k1_spi_dma_one() currently submits the TX DMA descriptor to the DMA engine
before preparing the RX DMA descriptor. If preparing the RX descriptor
subsequently fails, the function jumps to the fallback error path without
canceling or aborting the already submitted TX DMA descriptor.

Fix this by preparing both the TX and RX descriptors before submitting
either of them to the DMA engine.
