spi: spacemit: fix dangling TX DMA descriptor on RX prep failure

Browse source

In k1_spi_dma_one(), the TX DMA descriptor is submitted via
dmaengine_submit() before the RX descriptor is prepared.  If
k1_spi_dma_prep() fails for RX, the function jumps to the fallback
path without terminating the already-submitted TX descriptor.

So terminate the TX channel with dmaengine_terminate_sync() when RX
descriptor preparation fails.
