ASoC: sh: rz-ssi: Improve error handling in rz_ssi_probe() error path



We usually do cleanup in reverse order of init. Currently in case of
error rz_ssi_release_dma_channels() done in the reverse order. This
patch improves error handling in rz_ssi_probe() error path.

While at it, use "goto cleanup" style to reduce code duplication.
