After commit 7d7cbeaba5b7 ("PCI/ERR: Clear status of the reporting
device"), the AER status of the device that reported the error
rather than the first downstream port is cleared. So the problem
in commit aa344bc8b727 ("PCI/ERR: Clear AER status only when we
control AER") is no longer existent, and we change to use
pcie_aer_is_native() here.
pci_aer_clear_nonfatal_status() already has pcie_aer_is_native(),
so we move pci_aer_clear_nonfatal_status() out of
pcie_aer_is_native().
Replace statements that judge whether OS owns AER in
get_port_device_capability() with pcie_aer_is_native().
