In DPC service enable logic, check for services & PCIE_PORT_SERVICE_AER implies pci_aer_available() is true. So there is no need to explicitly check it again. Also, passing pcie_ports=dpc-native in kernel command line implies DPC needs to be enabled in native mode irrespective of AER ownership status. So checking for pci_aer_available() without checking for pcie_ports status is incorrect.
