[PATCH v3] PCI/ERR: Use pcie_aer_is_native() to judge whether OS owns AER

[Zhuo Chen]

Use pcie_aer_is_native() in place of "host->native_aer ||
pcie_ports_native" to judge whether OS has native control of AER
in pcie_do_recovery().

Replace "dev->aer_cap && (pcie_ports_native || host->native_aer)" in
get_port_device_capability() with pcie_aer_is_native(), which has no
functional changes.

Changelog:
v3:
- Simplify why we use pcie_aer_is_native().
- Revert modification of pci_aer_clear_nonfatal_status() and comments.
v2:
- Add details and note in commit log.
