It would be better to enforce this constraint at runtime.

e.g. set some global variable that forbids device removal
and warn in the kernel log. In theory this could be also
done per device, but I guess that would be more effort.

Of course it cannot prevent the user from really removing
a device, but at least the pci_dev could stay around.
