I don't know enough about pci/cardbus, but in
arch/i386/pci.c::pcibios_assign_resources, I can see the following :

if (!r->start && r->end)
pci_assign_resource(dev, idx);

without testing the result and without freeing the ressource for all
index if it fails on one index. So I don't know if your tests are necessary.
Beside that, testing (!r->start && r->end) seems to be more in sync
with arch/i386/pci.c than testing r->flags
