Nikita Zhandarovich 9fc2e7f2cf ASoC: fsl_asrc_dma: fix potential null-ptr-deref 
commit 86a24e99c9 upstream.

dma_request_slave_channel() may return NULL which will lead to
NULL pointer dereference error in 'tmp_chan->private'.

Correct this behaviour by, first, switching from deprecated function
dma_request_slave_channel() to dma_request_chan(). Secondly, enable
sanity check for the resuling value of dma_request_chan().
Also, fix description that follows the enacted changes and that
concerns the use of dma_request_slave_channel().

Fixes: 706e2c8811 ("ASoC: fsl_asrc_dma: Reuse the dma channel if available in Back-End")
