usb: dwc3: qcom: Release the correct resources in dwc3_qcom_remove()

In the probe, some resources are allocated with
dwc3_qcom_of_register_core() or dwc3_qcom_acpi_register_core(). The
corresponding resources are already coorectly freed in the error handling
path of the probe, but not in the remove function.

Fix it.
