[PATCH] pciconf -e to list PCI errors

So this is a bit hackish, but this patch provides a simple way to see if
any PCI errors have occurred on a system.  If we grew real AER support
in the kernel we might want to then rip this out (which is why I hadn't
posted this earlier).  However, this might be useful as an intermediate
step.
