x86/PCI-MSI: properly determine VF BAR values

As was discussed a couple of times on this list, SR-IOV virtual
functions have their BARs read as zero - the physical function's
SR-IOV capability structure must be consulted instead. The bogus
warnings people complained about are being eliminated with this
change.
