Today we read PCI VENDOR-ID in order to make sure PCI link is
healthy. Apparently the VENDOR-ID might be stored on host and
hence, when we read it we might not access the PCI bus.
In order to make sure PCI health check is reliable, we will start
checking the DEVICE-ID instead.
What's keeping some system from caching that as well?
Since this is checking for PCIe link health, it will be 0xFF when bad.
Checking some part of Config Space that is writable would be more reliable.
