[PATCH] spi: spi-fsl-dspi: Fill actual_length when doing DMA transfer

Users of SPI device drivers may rely on 'actual_length', so it is important that information is correctly reported. One example would be spi_mem_exec_op() which will fail if 'actual_length' doesn't match requested transfer length. To fix the problem, add necessary code to populate 'actual_length'.
