PCI: dwc: Use PTR_ERR_OR_ZERO to simplify code
Use PTR_ERR_OR_ZERO rather than if(IS_ERR(...)) + PTR_ERR to avoid the
following warnings found by scripts/coccinelle/api/ptr_ret.cocci:
drivers/pci/dwc/pcie-qcom.c:215:1-3: WARNING: PTR_ERR_OR_ZERO can be used
drivers/pci/dwc/pcie-qcom.c:247:1-3: WARNING: PTR_ERR_OR_ZERO can be used
drivers/pci/dwc/pcie-qcom.c:481:1-3: WARNING: PTR_ERR_OR_ZERO can be used
