spi: rockchip: potential NULL dereference on error
We were calling dma_release_channel(rs->dma_tx.ch) when "rs->dma_tx.ch"
is potentially NULL. There is actually a call to that in the unwind
code at the bottom of the function so we can just re-arrange this a bit
and remove the call. Also there is no need to set rs->dma_tx.ch to
NULL on this error path.
