The nVidia CK804 PCI-E chipset supports the AER extended capability
but sometimes fails to link it (with some BIOS or after a warm reboot).
It makes the AER cap invisible to pci_find_ext_capability().

The patch adds a quirk to set the missing bit that controls the
linking of the capability.
By the way, it removes the corresponding code in the myri10ge driver.
