[PATCH 1/4] ALSA: usb-audio: qcom: Improve error logging in USB offload

[wangdich9700]

From: wangdicheng <wangdicheng@xxxxxxxxxx>

Add error codes to error messages for better debugging.
This helps identify the root cause when USB audio offload fails.

Error messages now include the actual error code returned by
xhci_sideband operations, making it easier to diagnose failures
during USB audio offload setup.
