ASoC: sh: rz-ssi: Improve error handling in rz_ssi_dma_request function
dma_request_chan() returns error pointer in case of failures, but
the rz_ssi_dma_request() checked for NULL pointer instead.
This patch fixes the issue by checking for ERR_PTR() instead of
NULL and sets the DMA pointers to NULL in error case so that ssi
can fallback to PIO mode.
Fixes: 26ac471c5354 ("ASoC: sh: rz-ssi: Add SSI DMAC support")
