ASoC: sh: rz-ssi: Release the DMA channels in rz_ssi_probe() error path
DMA channels requested by rz_ssi_dma_request() in rz_ssi_probe() were
never released in the error path apart from one place. This patch fixes
this issue by calling rz_ssi_release_dma_channels() in the error path.
Fixes: 26ac471c5354 ("ASoC: sh: rz-ssi: Add SSI DMAC support")
