spi: stm32: fix missing pointer assignment in case of dma chaining

Browse source 
Commit c4f2c05ab0 ("spi: stm32: fix pointer-to-pointer variables usage")
introduced a regression since dma descriptors generated as part of the
stm32_spi_prepare_rx_dma_mdma_chaining function are not well propagated
to the caller function, leading to mdma-dma chaining being no more
functional.
