PCI: dwc: Perform cleanup in the error path of dw_pcie_resume_noirq()

PCI: dwc: Perform cleanup in the error path of dw_pcie_resume_noirq()

If the dw_pcie_resume_noirq() API fails, it just returns the errno without
doing cleanup in the error path, leading to resource leak.

So perform cleanup in the error path.
