[PATCH] myri10ge - drop workaround for the missing AER ext cap on nVidia CK804

We don't need to hardcode the AER capability of the nVidia CK804 chipset
anymore since commit cf34a8e0 (PCI: nVidia
quirk to make AER PCI-E extended capability visible) now makes sure that
this cap will be available to pci_find_ext_capability().
