[PATCH 2/3] USB: dwc3: qcom: fix software node leak on probe errors

[Johan Hovold <johan+linaro@kernel.org>]

Make sure to remove the software node also on (ACPI) probe errors to
avoid leaking the underlying resources.

Note that the software node is only used for ACPI probe so the driver
unbind tear down is updated to match probe.
