[PATCH 1/2] ASoC: xilinx: xlnx_i2s: Use dev_err_probe() and drop redundant error handling

[phucduc.bui@gmail.com]

From: bui duc phuc <phucduc.bui@gmail.com>

Use dev_err_probe() for probe error handling where appropriate to
simplify the code and properly handle deferred probe.
Also remove redundant error messages when the called helper already
reports failures, returning the error directly to avoid duplicate
logging.
