[PATCH v2 2/3] ASoC: xilinx: xlnx_spdif: Preserve devm_request_irq() error codes

[phucduc.bui at gmail.com]

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

devm_request_irq() can return various error codes, such as -EINVAL,
-ENOTCONN, -ENOMEM, -ENOSYS, and -EBUSY. However, the driver
overwrites all of them with -ENODEV, which hides the actual cause of
the failure.
Also, devm_request_irq() already reports failures internally, so the
additional dev_err() call is redundant.
Return the original error code and remove the duplicate error message.
