ixgbe probe failure on Proxmox 8

[Bjorn Helgaas <helgaas@kernel.org>]

Just a heads-up about an ixgbe probe failure seen with Proxmox 8.  I
suspect this is a PCI core problem, probably not an ixgbe problem.

The ixgbe device logs an Advisory Non-Fatal Error and it seems like
subsequent reads from the device return ~0:

  pcieport 0000:00:03.1: AER: Corrected error received: 0000:05:00.0
  pci 0000:05:00.0: PCIe Bus Error: severity=Corrected, type=Transaction Layer, (Receiver ID)
  pci 0000:05:00.0:   device [8086:1563] error status/mask=00002000/00000000
  pci 0000:05:00.0:    [13] NonFatalErr

  ixgbe 0000:05:00.0: enabling device (0000 -> 0002)
  ixgbe 0000:05:00.0: Adapter removed

I opened a bugzilla with complete dmesg log at
https://bugzilla.kernel.org/show_bug.cgi?id=218491 with some
speculation about what might have caused this, e.g., an ACS
configuration error or something.  It's lame, I know, so this is just
a shot in the dark.
