Heyi Guo 710d9e69fa MdeModulePkg/NonDiscoverable: fix memory override bug
For PciIoPciRead interface, memory prior to Buffer would be written
with zeros if Offset was larger than sizeof (Dev->ConfigSpace), which
would cause serious system exception.

So we add a pre-check branch to avoid memory override.
