[PATCH v8 4/5] PCI/portdrv: Remove redundant pci_aer_available() check in DPC enable logic

From: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@linux.intel.com>

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.
